Merge tag 'sound-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound
Pull sound updates from Takashi Iwai: "It's a relatively calm development cycle, but still lots of updates in the driver side like Intel SOF. Below are some highlights: ALSA / ASoC core: - A new kselftest for ALSA control API - PCM NO_REWINDS support - Potential race fixes around control removals - Unify x86 SG-buffer memory allocation code - Cleanups and race fixes for ASoC DPCM locking ASoC: - Refinements and cleanups around the delay() APIs - Wider use of dev_err_probe(). - Continuing cleanups and improvements to the SOF code - Support for pin switches in simple-card derived cards - Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20 S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments TLV320ADC3xxx HD-audio / USB-audio: - Fix deadlock at HD-audio codec unbinding - Fixes for Tegra194 HD-audio, new HDA support for CS35L41 codec - Quirks for Lenovo and HP machines, Gigabyte mobo, Bose device Misc: - Fix virmidi drain behavior Note that the merge of CS35L41 codec support is still half-baked, and at least one ACPI change is missing. Although this won't hinder the kernel build itself, we're going to catch up before RC1" * tag 'sound-5.17-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (415 commits) ALSA: hda: intel-dsp-config: reorder the config table ALSA: hda: intel-dsp-config: add JasperLake support ALSA: hda: cs35l41: fix double free on error in probe() ALSA: hda: Fix dependencies of CS35L41 on SPI/I2C buses ALSA: hda: Fix dependency on ASoC cs35l41 codec ASoC: cs35l41: Add support for hibernate memory retention mode ASoC: cs35l41: Update handling of test key registers ALSA: intel_hdmi: Check for error num after setting mask ASoC: wcd9335: Keep a RX port value for each SLIM RX mux ASoC: amd: acp: acp-mach: Change default RT1019 amp dev id ALSA: virmidi: Remove duplicated code ALSA: seq: virmidi: Add a drain operation ASoC: topology: Fix typo ASoC: fsl_asrc: refine the check of available clock divider ASoC: Intel: bytcr_rt5640: Add support for external GPIO jack-detect ASoC: Intel: bytcr_rt5640: Support retrieving the codec IRQ from the AMCR0F28 ACPI dev ASoC: rt5640: Add support for boards with an external jack-detect GPIO ASoC: rt5640: Allow snd_soc_component_set_jack() to override the codec IRQ ASoC: rt5640: Change jack_work to a delayed_work ASoC: rt5640: Fix possible NULL pointer deref on resume ...
