sound fixes for 5.3-rc2

Browse Source 
All relative small changes.
 
 - A regression fix for PCM link code with CONFIG_REFCOUNT_FULL;
   stumbled on a slight difference between atomic_t and refcount_t
 
 - A couple of HD-audio stabilization patches addressing the too
   slow PM resume seen on some Intel chips
 
 - A series of ALSA compress-offload API fixes, including the
   regression by the previous capture stream support
 
 - Trivial LINE6 USB-audio driver fixes, a new Conexant HD-audio
   chip coverage, and a fix in AC97 bus error path
