ALSA: hda - Fix path power activation

2015-08-25T05:59:02+00:00

The widget power-saving code tries to turn up/down the power of each widget in the I/O paths that are modified at each jack plug/unplug. The recent report revealed that the power activation leaves some widgets unpowered after plugging. This is because snd_hda_activate_path() turns on path->active flag at the end of the function while the path power management is done before that. Then it's regarded as if nothing is active, and the driver turns off the power. The fix is simply to set the flag at the beginning of the function, before trying to power up.

ALSA: hda - Check all inputs for is_active_nid_for_any()

2015-08-25T05:59:01+00:00

The is_active_nid_for_any() function in the generic parser is supposed to check all connections from/to the given widget, but the current code checks only the first input connection (index = 0). This patch corrects the code to check all inputs by passing -1 to index argument. Bugzilla: https://bugzilla.kernel.org/show_bug.cgi?id=102521 Cc: [v4.1+] Signed-off-by: Takashi Iwai

ALSA: hda: fix possible NULL dereference

2015-08-24T13:02:03+00:00

After a for-loop was replaced by list_for_each_entry, see Commit bbbc7e8502c9 ("ALSA: hda - Allocate hda_pcm objects dynamically"), Commit 751e2216899c ("ALSA: hda: fix possible null dereference"), a possible NULL pointer dereference has been introduced; this patch adds the NULL check on pcm->pcm, while leaving a potentially superfluous check on pcm itself untouched.

ALSA: hda - Shutdown CX20722 on reboot/free to avoid spurious noises

2015-08-21T08:28:00+00:00

On shutdown/reboot of CX20722, first shut down all EAPDs, then shut down the afg node to D3. Failure to do so can lead to spurious noises from the internal speaker directly after reboot (and before the codec is reinitialized again, i e in BIOS setup or GRUB menus).

Merge tag 'asoc-v4.2-disable-topology' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

2015-08-19T16:31:54+00:00

ASoC: Disable topology support for v4.2 The topology code merged in the v4.2 merge window introduced a new ABI which was believed to be suitable for use but subsequently additional work by the developers of this feature have revealed some problems that need to be addressed. In order to allow this to be done without having to support the initial ABI add Kconfig to disable the build and also add some #error statements to the UAPI header so users can't use them.

ALSA: usb-audio: Fix runtime PM unbalance

2015-08-19T12:57:51+00:00

The fix for deadlock in PM in commit [1ee23fe07ee8: ALSA: usb-audio: Fix deadlocks at resuming] introduced a new check of in_pm flag. However, the brainless patch author evaluated it in a wrong way (logical AND instead of logical OR), thus usb_autopm_get_interface() is wrongly called at probing, leading to unbalance of runtime PM refcount. This patch fixes it by correcting the logic. Reported-by: Hans Yang Fixes: 1ee23fe07ee8 ('ALSA: usb-audio: Fix deadlocks at resuming') Cc: [v3.15+] Signed-off-by: Takashi Iwai

ASoC: topology: Add Kconfig option for topology

2015-08-18T05:45:47+00:00

Allow the topology code to be compiled out so that users who don't need topology don't need to havve the code compiled in, saving them some memory. Some more configuration could be added to remove some of the hooks into the core data structures but that is probably best done with some refactoring to use functions to do the updates of the data structures rather than ifdefing in the code as we'd need to do at the minute.

ALSA: hda - Fix the white noise on Dell laptop

Dell laptop causes the white noise by login screen and headphone, and the fixup function ALC292_FIXUP_DISABLE_AAMIX can eliminate this noise.
