Subject: ALSA: hda - Remove old codec-probe limitation
X-Git-Tag: firefly_0821_release~15381^2~45^2~98
X-Git-Url: http://demsky.eecs.uci.edu/git/?a=commitdiff_plain;h=34c25350acfc792747e861d1e36874abf7e73255;p=firefly-linux-kernel-4.4.55.git

ALSA: hda - Remove old codec-probe limitation

Removed the old workaround to avoid the non-existing codec slot.
The current code should work without that workaround.  If any,
we can add a quirk table.
