sound fixes for 5.3-rc7 

A collection of small fixes as usual:
 
 - More coverage of USB-audio descriptor sanity checks
 - A fix for mute LED regression on Conexant HD-audio codecs
 - A few device-specific fixes and quirks for USB-audio and HD-audio
 - A fix for (die-hard remaining) possible race in sequencer core
 - FireWire oxfw regression fix that was introduced in 5.3-rc1
