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"
