Subject: ALSA: hda - Fix missing CA initialization for HDMI/DP
From: Takashi Iwai <[email protected]>
commit 11839aed21881d7edd65dd79f22a8eb18426f672 upstream.
The commit 53d7d69d8ffdfa60c5b66cc2e9ee0774aaaef5c0
ALSA: hdmi - support infoframe for DisplayPort
dropped the initialization of CA field accidentally.
This resulted in only two-channel LPCM mode on Nvidia machines.
