Subject: ALSA: hda - Remove old codec-probe limitation
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=34c25350acfc792747e861d1e36874abf7e73255;p=linux-beck.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.
