Merge tag 'sound-fix-7.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "A collection of small bug fixes accumulated over the last week.
  Most are device-specific fixes while there are a few core fixes as
  well.

  Here are the highlights:

  ALSA Core:
   - A fix for an uninitialised heap leak in ALSA sequencer core
   - A fix for error handling/resource leak in compress-offload API

  USB-audio:
   - A teardown-ordering fix in USB MIDI 2.0 to prevent use-after-free
   - Bounds and length checks for packet data in Native Instruments
     caiaq / Traktor Kontrol input parsers
   - Avoidance of expensive kobject path lookups in DualSense controller
     matches
   - Robustness/memory leak fixes for Qualcomm USB offload driver
   - Focusrite Control Protocol (FCP) NULL-pointer dereference fix and a
     new device quirk (ISA C8X)
   - Device-specific quirks for Yamaha CDS3000 and SC13A

  HD-Audio:
   - A bunch of quirks and mute/mic-mute LED fixups for various laptops
     (Acer, Clevo, Lenovo, HP)

  ASoC & SoundWire:
   - Avoid failing card registration if the device_link creation fails
   - A workaround for SoundWire randconfig build failures by making
     helper functions static inline
   - Corrected MCLK reference validation for CS530x codecs
   - Clean up of untested, problematic guard() macro replacements in
     Rockchip SAI driver
   - Fix for eDMA maxburst misalignment with channel count in Freescale
     ASRC
   - Miscellaneous hardware-specific fixes (qcom, rt5650, tlv320aic3x,
     tas2781/3)

  Others:
   - Bounds and length checks for packet data in Apple iSight"
