Merge tag 'sound-5.5-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound

Pull sound fixes from Takashi Iwai:
 "A slightly high amount at this time, but all good and small fixes:

   - A PCM core fix that initializes the buffer properly for avoiding
     information leaks; it is a long-standing minor problem, but good to
     fix better now

   - A few ASoC core fixes for the init / cleanup ordering issues that
     surfaced after the recent refactoring

   - Lots of SOF and topology-related fixes went in, as usual as such
     hot topics

   - Several ASoC codec and platform-specific small fixes: wm89xx,
     realtek, and max98090, AMD, Intel-SST

   - A fix for the previous incomplete regression of HD-audio, now
     hitting Nvidia HDMI

   - A few HD-audio CA0132 codec fixes"
