ALSA: hda - Don't trust codec EPSS bit for IDT 92HD83xx & co
Browse files Browse the repository at this point in the history
These codecs seem reporting EPSS but require longer delay for the
proper D3 transition.  For example, D3_STOP_CLOCK_OK bit won't be set
correctly even after D3.

In this patch, codec->epss flag is overridden for avoid the
misbehavior.
