Pull sound updates from Takashi Iwai: "This became again a busy development cycle. There are few ALSA core updates (merely API cleanups and sparse fixes), with the majority of other changes are found in ASoC scene. Here are some highlights: ALSA core: - More helper macros for sparse warning fixes (e.g. bitwise types) - Slight optimization of PCM OSS locks - Make common handling for PCM / compress buffers (for SOF) ASoC: - Lots of code refactoring and modernization for (still ongoing) componentization works - Conversion of SND_SOC_ALL_CODECS to use imply - Continued refactoring and fixing of the Intel SOF/SST support, including the initial (but still incomplete) SoundWire support - SoundWire and more advanced clocking support for Realtek RT5682 - Support for amlogic GX, Meson 8, Meson 8B and T9015 DAC, Broadcom DSL/PON, Ingenic JZ4760 and JZ4770, Realtek RL6231, and TI TAS2563 and TLV320ADCX140 HD-audio: - Optimizations in HDMI jack handling - A few new quirks and fixups for Realtek codecs USB-audio: - Delayed registration support - New quirks for Motu, Kingston, Presonus" * tag 'sound-5.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (415 commits) ALSA: usb-audio: Fix case when USB MIDI interface has more than one extra endpoint descriptor Revert "ALSA: uapi: Drop asound.h inclusion from asoc.h" ALSA: hda/realtek - Remove now-unnecessary XPS 13 headphone noise fixups ALSA: hda/realtek - Set principled PC Beep configuration for ALC256 ALSA: doc: Document PC Beep Hidden Register on Realtek ALC256 ALSA: hda/realtek - a fake key event is triggered by running shutup ALSA: hda: default enable CA0132 DSP support ASoC: amd: acp3x-pcm-dma: clean up two indentation issues ASoC: tlv320adcx140: Remove undocumented property ASoC: Intel: sof_sdw: Add Volteer support with RT5682 SNDW helper function ASoC: Intel: common: add match table for TGL RT5682 SoundWire driver ASoC: Intel: boards: add sof_sdw machine driver ASoC: Intel: soc-acpi: update topology and driver name for SoundWire platforms ASoC: rt5682: move DAI clock registry to I2S mode ASoC: pxa: magician: convert to use i2c_new_client_device() ASoC: SOF: Intel: hda-ctrl: add reset cycle before parsing capabilities Asoc: SOF: Intel: hda: check SoundWire wakeen interrupt in irq thread ASoC: SOF: Intel: hda: add WAKEEN interrupt support for SoundWire ASoC: SOF: Intel: hda: add parameter to control SoundWire clock stop quirks ASoC: SOF: Intel: hda: merge IPC, stream and SoundWire interrupt handlers ...

sound: Call cpu_latency_qos_() instead of pm_qos_()

2020-02-14T09:37:25Z

Call cpu_latency_qos_add/update/remove_request() and cpu_latency_qos_request_active() instead of pm_qos_add/update/remove_request() and pm_qos_request_active(), respectively, because the latter are going to be dropped.

ALSA: pcm: Fix double hw_free calls

2020-02-13T15:30:22Z

The commit 66f2d19f8116 ("ALSA: pcm: Fix memory leak at closing a stream without hw_free") tried to fix the regression wrt the missing hw_free call at closing without SNDRV_PCM_IOCTL_HW_FREE ioctl. However, the code change dropped mistakenly the state check, resulting in calling hw_free twice when SNDRV_PCM_IOCTL_HW_FRE got called beforehand. For most drivers, this is almost harmless, but the drivers like SOF show another regression now. This patch adds the state condition check before calling do_hw_free() at releasing the stream for avoiding the double hw_free calls.

ALSA: pcm: Use a macro for parameter masks to reduce the needed cast

2020-02-10T07:27:51Z

The parameter bit mask needs often explicit cast with __force, e.g. for the PCM subformat type. Instead of adding __force at each place, which is error prone, this patch introduces a new macro and replaces the all bit shift with it. This fixes the sparse warnings like the following: sound/core/pcm_native.c:2508:30: warning: restricted snd_pcm_access_t degrades to integer No functional changes, just sparse warning fixes.

ALSA: pcm: Fix sparse warnings wrt snd_pcm_state_t

2020-01-31T15:23:13Z

Since we have a bitwise definition of snd_pcm_state_t and use it for certain struct fields, a few new (and years old) sparse warnings came up. This patch is an attempt to cover them. - The state fields in snd_pcm_mmap_status* and co are all defined as snd_pcm_state_t type now - The PCM action callbacks take snd_pcm_state_t argument as well; some actions taking special values got the explicit cast and comments - For the PCM action that doesn't need an extra argument receives ACTION_ARG_IGNORE instead of ambiguous 0 While we're at it, the boolean argument is also properly changed to bool and true/false, as well as a slight refactoring of PCM pause helper function to make easier to read. No functional changes, just shutting up chatty sparse.

ALSA: pcm: Fix memory leak at closing a stream without hw_free

2020-01-29T20:01:19Z

ALSA PCM core recently introduced a new managed PCM buffer allocation mode that does allocate / free automatically at hw_params and hw_free. However, it overlooked the code path directly calling hw_free PCM ops at releasing the PCM substream, and it may result in a memory leak as spotted by syzkaller when no buffer preallocation is used (e.g. vmalloc buffer). This patch papers over it with a slight refactoring. The hw_free ops call and relevant tasks are unified in a new helper function, and call it from both places.

ALSA: pcm: Make snd_pcm_hw_constraints_init() and _complete() static

Both snd_pcm_hw_constraints_init() and _complete() functions are called only from pcm_native.c, hence they can be static for further optimization. Link: https://lore.kernel.org/r/20200116162825.24792-1-tiwai@suse.de Signed-off-by: Takashi Iwai
