Merge tag 'sound-6.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound updates from Takashi Iwai:
 "This was a relatively calm development cycle. Most of changes are
  rather small device-specific fixes and enhancements. The only
  significant changes in ALSA core are code refactoring with the recent
  cleanup infrastructure, which should bring no functionality changes.
  Some highlights below:

  Core:
   - Lots of cleanups in ALSA core code with automatic kfree cleanup and
     locking guard macros
   - New ALSA core kunit test

  ASoC:
   - SoundWire support for AMD ACP 6.3 systems
   - Support for reporting version information for AVS firmware
   - Support DSPless mode for Intel Soundwire systems
   - Support for configuring CS35L56 amplifiers using EFI calibration
     data
   - Log which component is being operated on as part of power
     management trace events.
   - Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x

  HD- and USB-audio:
   - More Cirrus HD-audio codec support
   - TAS2781 HD-audio codec fixes
   - Scarlett2 mixer fixes

  Others:
   - Enhancement of virtio driver for audio control supports
   - Cleanups of legacy PM code with new macros
   - Firewire sound updates"
