2022-07-21ASoC: dapm: Initialise kcontrol data for mux/demux controlsCharles Keepax1-0/+5
[ Upstream commit 11d7a12f7f50baa5af9090b131c9b03af59503e7 ] DAPM keeps a copy of the current value of mux/demux controls, however this value is only initialised in the case of autodisable controls. This leads to false notification events when first modifying a DAPM kcontrol that has a non-zero default. Autodisable controls are left as they are, since they already initialise the value, and there would be more work required to support autodisable muxes where the first option isn't disabled and/or that isn't the default. Technically this issue could affect mixer/switch elements as well, although not on any of the devices I am currently running. There is also a little more work to do to address the issue there due to that side supporting stereo controls, so that has not been tackled in this patch.

2022-06-09ASoC: dapm: Don't fold register value changes into notificationsMark Brown1-2/+0
[ Upstream commit ad685980469b9f9b99d4d6ea05f4cb8f57cb2234 ] DAPM tracks and reports the value presented to the user from DAPM controls separately to the register value, these may diverge during initialisation or when an autodisable control is in use. When writing DAPM controls we currently report that a change has occurred if either the DAPM value or the value stored in the register has changed, meaning that if the two are out of sync we may appear to report a spurious event to userspace. Since we use this folded in value for nothing other than the value reported to userspace simply drop the folding in of the register change.

2022-04-27ASoC: soc-dapm: fix two incorrect uses of list iteratorXiaomeng Tong1-4/+2
commit f730a46b931d894816af34a0ff8e4ad51565b39f upstream. These two bug are here: list_for_each_entry_safe_continue(w, n, list, power_list); list_for_each_entry_safe_continue(w, n, list, power_list); After the list_for_each_entry_safe_continue() exits, the list iterator will always be a bogus pointer which point to an invalid struct objdect containing HEAD member. The funciton poniter 'w->event' will be a invalid value which can lead to a control-flow hijack if the 'w' can be controlled. The original intention was to continue the outer list_for_each_entry_safe() loop with the same entry if w->event is NULL, but misunderstanding the meaning of list_for_each_entry_safe_continue(). So just add a 'continue;' to fix the bug.

2021-11-26ASoC: DAPM: Cover regression by kctl change notification fixTakashi Iwai1-6/+23
commit 827b0913a9d9d07a0c3e559dbb20ca4d6d285a54 upstream. The recent fix for DAPM to correct the kctl change notification by the commit 5af82c81b2c4 ("ASoC: DAPM: Fix missing kctl change notifications") caused other regressions since it changed the behavior of snd_soc_dapm_set_pin() that is called from several API functions. Formerly it returned always 0 for success, but now it returns 0 or 1. This patch addresses it, restoring the old behavior of snd_soc_dapm_set_pin() while keeping the fix in snd_soc_dapm_put_pin_switch().

2021-10-27ASoC: DAPM: Fix missing kctl change notificationsTakashi Iwai1-5/+8
commit 5af82c81b2c49cfb1cad84d9eb6eab0e3d1c4842 upstream. The put callback of a kcontrol is supposed to return 1 when the value is changed, and this will be notified to user-space. However, some DAPM kcontrols always return 0 (except for errors), hence the user-space misses the update of a control value. This patch corrects the behavior by properly returning 1 when the value gets updated.

2021-01-19ASoC: dapm: remove widget from dirty list on freeThomas Hebb1-0/+1
commit 5c6679b5cb120f07652418524ab186ac47680b49 upstream. A widget's "dirty" list_head, much like its "list" list_head, eventually chains back to a list_head on the snd_soc_card itself. This means that the list can stick around even after the widget (or all widgets) have been freed. Currently, however, widgets that are in the dirty list when freed remain there, corrupting the entire list and leading to memory errors and undefined behavior when the list is next accessed or modified. I encountered this issue when a component failed to probe relatively late in snd_soc_bind_card(), causing it to bail out and call soc_cleanup_card_resources(), which eventually called snd_soc_dapm_free() with widgets that were still dirty from when they'd been added.

2020-09-28ASoC: soc-dai: add mark for snd_soc_dai_startup/shutdown()Kuninori Morimoto1-2/+2
soc_pcm_open() does rollback when failed (A), but, it is almost same as soc_pcm_close(). static int soc_pcm_open(xxx) { ... if (ret < 0) goto xxx_err; ... return 0; ^ config_err: | ... | rtd_startup_err: (A) ... | component_err: | ... v return ret; } The difference is soc_pcm_close() is for all dai/component/substream, rollback is for succeeded part only. This kind of duplicated code can be a hotbed of bugs, thus, we want to share soc_pcm_close() and rollback. Now, soc_pcm_open/close() are handling => 1) snd_soc_dai_startup/shutdown() 2) snd_soc_link_startup/shutdown() 3) snd_soc_component_module_get/put() 4) snd_soc_component_open/close() 5) pm_runtime_put/get() This patch is for 1) snd_soc_dai_startup/shutdown(). The idea of having bit-flag or counter is not enough for this purpose. For example if one DAI is used for 2xPlaybacks for some reasons, and if 1st Playback was succeeded but 2nd Playback was failed, 2nd Playback rollback doesn't need to call shutdown. But it has succeeded bit-flag or counter via 1st Playback, thus, 2nd Playback rollback will call unneeded shutdown. And 1st Playback's necessary shutdown will not be called, because bit-flag or counter was cleared by wrong 2nd Playback rollback. To avoid such case, this patch marks substream pointer when startup() was succeeded. If rollback needed, it will check rollback flag and marked substream pointer. One note here is that it cares *current* startup() only now. but we might want to check *whole* marked substream in the future. This patch is using macro named "push/pop", so that it can be easily update.

2020-07-24ASoC: dapm: don't call pm_runtime_* on card deviceTzung-Bi Shih1-2/+2
runtime_usage of sound card has been observed to grow without bound. For example: $ cat /sys/devices/platform/sound/power/runtime_usage 46 $ sox -n -t s16 -r 48000 -c 2 - synth 1 sine 440 vol 0.1 | \ aplay -q -D hw:0,0 -f S16_LE -r 48000 -c 2 $ cat /sys/devices/platform/sound/power/runtime_usage 52 Commit 4e872a46823c ("ASoC: dapm: Don't force card bias level to be updated") stops to force update bias_level on card. If card doesn't provide set_bias_level callback, the snd_soc_dapm_set_bias_level() is equivalent to NOP for card device. As a result, dapm_pre_sequence_async() doesn't change the bias_level of card device correctly. Thus, pm_runtime_get_sync() would be called in dapm_pre_sequence_async() without symmetric pm_runtime_put() in dapm_post_sequence_async(). Don't call pm_runtime_* on card device.

2020-06-22ASoC: soc-component: merge snd_soc_component_read() and ↵Kuninori Morimoto1-20/+11
snd_soc_component_read32() We had read/write function for Codec, Platform, etc, but these has been merged into snd_soc_component_read/write(). Internally, it is using regmap or driver function. In read case, each styles are like below regmap ret = regmap_read(..., reg, &val); driver function val = xxx->read(..., reg); Because of this kind of different style, to keep same read style, when we merged each read function into snd_soc_component_read(), we created snd_soc_component_read32(), like below. commit 738b49efe6c6 ("ASoC: add snd_soc_component_read32") (1) val = snd_soc_component_read32(component, reg); (2) ret = snd_soc_component_read(component, reg, &val); Many drivers are using snd_soc_component_read32(), and some drivers are using snd_soc_component_read() today. In generally, we don't check read function successes, because, we will have many other issues at initial timing if read function didn't work. Now we can use soc_component_err() when error case. This means, it is easy to notice if error occurred. This patch aggressively merge snd_soc_component_read() and _read32(), and makes snd_soc_component_read/write() as generally style. This patch do 1) merge snd_soc_component_read() and snd_soc_component_read32() 2) it uses soc_component_err() when error case (easy to notice) 3) keeps read32 for now by #define 4) update snd_soc_component_read() for all drivers Because _read() user drivers are not too many, this patch changes all user drivers.

The newly added CODEC to CODEC DAI link widget pointers in snd_soc_dai_link are better placed in snd_soc_pcm_runtime. snd_soc_dai_link is really intended for static configuration of the DAI, and the runtime for dynamic data. The snd_soc_dai_link structures are not destroyed if the card is unbound. The widgets are cleared up on unbind, however if the card is rebound as the snd_soc_dai_link structures are reused these pointers will be left at their old values, causing access to freed memory.

2020-04-14ASoC: dapm: Fix regression introducing multiple copies of DAI widgetsCharles Keepax1-43/+48
Refactoring was done to factor out the linking of DAI widgets into a helper function, dapm_add_valid_dai_widget. However when this was done, a regression was introduced for CODEC to CODEC links. It was over looked that the playback and capture variables persisted across all CODEC DAIs being processed, which ensured that the special DAI widget that is added for CODEC to CODEC links was only created once. This bug causes kernel panics during DAPM shutdown. To stick with the spirit of the original refactoring whilst fixing the issue, variables to hold the DAI widgets are added to snd_soc_dai_link. Furthermore the dapm_add_valid_dai_widget function is renamed to dapm_connect_dai_pair, the function only adds DAI widgets in the CODEC to CODEC case and its primary job is to add routes connecting two DAI widgets, making the original name quite misleading.

2020-02-28ASoC: dapm: Correct DAPM handling of active widgets during shutdownCharles Keepax1-1/+1
commit c2caa4da46a4 ("ASoC: Fix widget powerdown on shutdown") added a set of the power state during snd_soc_dapm_shutdown to ensure the widgets powered off. However, when commit 39eb5fd13dff ("ASoC: dapm: Delay w->power update until the changes are written") added the new_power member of the widget structure, to differentiate between the current power state and the target power state, it did not update the shutdown to use the new_power member. As new_power has not updated it will be left in the state set by the last DAPM sequence, ie. 1 for active widgets. So as the DAPM sequence for the shutdown proceeds it will turn the widgets on (despite them already being on) rather than turning them off.

2020-02-25ASoC: soc-pcm: move dpcm_path_put() to soc-pcm.cKuninori Morimoto1-0/+10
dpcm_path_put() (A) is calling kfree(*list). The freed list is created by dapm_widget_list_create() (B) which is called from snd_soc_dapm_dai_get_connected_widgets() (C) which is called from dpcm_path_get() (D). (B) dapm_widget_list_create(**list, ...) { ... => *list = kzalloc(); ... } (C) snd_soc_dapm_dai_get_connected_widgets(..., **list, ...) { ... dapm_widget_list_create(list, ...); ... } (D) dpcm_path_get(..., **list) { ... snd_soc_dapm_dai_get_connected_widgets(..., list, ...); ... } (A) dpcm_path_put(**list) { => kfree(*list); } This kind of unbalance code is very difficult to read/understand. To avoid this issue, this patch adds each missing paired function dapm_widget_list_free() for dapm_widget_list_create() (B), and snd_soc_dapm_dai_free_widgets() for snd_soc_dapm_dai_get_connected_widgets() (C). This patch uses these, and moves dpcm_path_put() next to dpcm_path_get().

2019-08-01ASoC: core: no need to check return value of debugfs_create functionsGreg Kroah-Hartman1-26/+4
When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. Also, there is no need to store the individual debugfs file name, just remove the whole directory all at once, saving a local variable. Note, the soc-pcm "state" file has now moved to a subdirectory, as it is only a good idea to save the dentries for debugfs directories, not individual files, as the individual file debugfs functions are changing to not return a dentry.
