   - wm_adsp: fixes for firmware unit tests
   - amd-yc: more DMI quirks for laptops
   - Minor fixes for fsl_xcvr and spacemit

  HD-Audio:
   - Mute LED and speaker quirks for HP, Lenovo, and Xiaomi laptops

  USB-audio:
   - New device-specific quirks (Motu, JBL, AlphaTheta, Razer)
   - Fix of MIDI2 playback on resume

  Others:
   - Firewire-tascam control event fix
   - Minor cleanups and fixes for sparc/dbri and pcmtest"
