sound fixes for 6.1-rc1

Browse Source 
Here are a few remaining patches for 6.1-rc1.  The major changes
 are the hibernation fixes for HD-audio CS35L41 codec and the
 USB-audio small fixes against the last change.  In addition, a
 couple of HD-audio regression fixes and a couple of potential
 mutex-deadlock fixes with OSS emulation in ALSA core side are seen.
