2021-08-09ALSA: pci: cs46xx: Fix set up buffer type properlyTakashi Iwai1-22/+8
CS46xx driver switches the buffer depending on the number of periods, and in some cases it switches to the own buffer without updating the buffer type properly. This may cause a problem with the mmap on exotic architectures that require the own mmap call for the coherent DMA buffer. This patch addresses the potential breakage by replacing the buffer setup with the proper macro. It also simplifies the source code, too.

2021-07-19ALSA: cs46xx: Allocate resources with device-managed APIsTakashi Iwai3-128/+38
This patch converts the resource management in PCI cs46xx driver with devres as a clean up. Each manual resource management is converted with the corresponding devres helper, and the card object release is managed now via card->private_free instead of a lowlevel snd_device. This should give no user-visible functional changes. Link: https://lore.kernel.org/r/20210715075941.23332-31-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>
2021-06-09ALSA: cs46xx: Fix assignment in if conditionTakashi Iwai3-30/+55
PCI CS46xx driver code contains a few assignments in if condition, which is a bad coding style that may confuse readers and occasionally lead to bugs. This patch is merely for coding-style fixes, no functional changes. Link: https://lore.kernel.org/r/20210608140540.17885-38-tiwai@suse.de Signed-off-by: Takashi Iwai <tiwai@suse.de>

git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound Pull sound updates from Takashi Iwai: "As the diffstat shows we've had again a lot of works done for this cycle: the majority of changes are the continued componentization and code refactoring in ASoC, the tree-wide PCM API updates and cleanups and SOF updates while a few ASoC driver updates are seen, too. Here we go, some highlights: Core: - Finally y2038 support landed to ALSA ABI; some ioctls have been extended and lots of tricks were applied - Applying the new managed PCM buffer API to all drivers; the API itself was already merged in 5.5 - The already deprecated dimension support in ALSA control API is dropped completely now - Verification of ALSA control elements to catch API misuses ASoC: - Further code refactorings and moving things to the component level - Lots of updates and improvements on SOF / Intel drivers; now including common HDMI driver and SoundWire support - New driver support for Ingenic JZ4770, Mediatek MT6660, Qualcomm WCD934x and WSA881x, and Realtek RT700, RT711, RT715, RT1011, RT1015 and RT1308 HD-audio: - Improved ring-buffer communications using waitqueue - Drop the superfluous buffer preallocation on x86 Others: - Many code cleanups, mostly constifications over the whole tree - USB-audio: quirks for MOTU, Corsair Virtuoso, Line6 Helix - FireWire: code refactoring for oxfw and dice drivers" * tag 'sound-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (638 commits) ALSA: usb-audio: add quirks for Line6 Helix devices fw>=2.82 ALSA: hda: Add Clevo W65_67SB the power_save blacklist ASoC: soc-core: remove null_snd_soc_ops ASoC: soc-pcm: add soc_rtd_trigger() ASoC: soc-pcm: add soc_rtd_hw_free() ASoC: soc-pcm: add soc_rtd_hw_params() ASoC: soc-pcm: add soc_rtd_prepare() ASoC: soc-pcm: add soc_rtd_shutdown() ASoC: soc-pcm: add soc_rtd_startup() ASoC: rt1015: add rt1015 amplifier driver ASoC: madera: Correct some kernel doc ASoC: topology: fix soc_tplg_fe_link_create() - link->dobj initialization order ASoC: Intel: skl_hda_dsp_common: Fix global-out-of-bounds bug ASoC: madera: Correct DMIC only input hook ups ALSA: cs46xx: fix spelling mistake "to" -> "too" ALSA: hda - Add docking station support for Lenovo Thinkpad T420s ASoC: Add MediaTek MT6660 Speaker Amp Driver ASoC: dt-bindings: rt5645: add suppliers ASoC: max98090: fix deadlock in max98090_dapm_put_enum_double() ASoC: dapm: add snd_soc_dapm_put_enum_double_locked ...

2018-06-13treewide: Use array_size() in vmalloc()Kees Cook1-2/+3
The vmalloc() function has no 2-factor argument form, so multiplication factors need to be wrapped in array_size(). This patch replaces cases of: vmalloc(a * b) with: vmalloc(array_size(a, b)) as well as handling cases of: vmalloc(a * b * c) with: vmalloc(array3_size(a, b, c)) This does, however, attempt to ignore constant size factors like: vmalloc(4 * 1024) though any constants defined via macros get caught up in the conversion.

snd_cs46xx_suspend() is missing snd_pcm_suspend_all calls for pcm_rear, pcm_center_lfe and pcm_iec958. There's also a copy/paste bug in snd_cs46xx_pcm_iec958(), overwriting pcm_rear in struct snd_cs46xx, leaving pcm_iec958 unused. Fix all this to allow all channels to survive suspend/resume.

This is a similar cleanup like the commit [3db084fd0af5: ALSA: fm801: PCI core handles power state for us]. Since pci_set_power_state(), pci_save_state() and pci_restore_state() are already done in the PCI core side, so we don't need to it doubly. Also, pci_enable_device(), pci_disable_device() and pci_set_master() calls in PM callbacks are superfluous nowadays, too, so get rid of them as well. Signed-off-by: Takashi Iwai <tiwai@suse.de>
