Series ALSA: Generic PCM copy ops using sockptr_t | expand

Commit Message

Takashi Iwai July 31, 2023, 3:47 p.m. UTC 
Along with the conversion to PCM copy ops, use the sockptr_t for the
pointer to be passed to the dmaengine process callback, too.  It
avoids the direct reference of sockptr.kernel field, and it can
potentially help for the drivers to access memory properly (although
both atmel and stm drivers don't use the given buffer address at
all for now).
