Subject: ALSA: hda - Return error for invalid setup for VIA
X-Git-Tag: v3.1-rc2~4^2~47^2~69^2~25
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7f0df88ce0ad846b68156b73b3acc9f3901989d3;p=platform%2Fkernel%2Flinux-stable.git

ALSA: hda - Return error for invalid setup for VIA

Instead of ignoring the invalid pin configuration, return the error.
This will avoid unexpected crash, anyway.
