Subject: ALSA: HDA: Fixup unnecessary volume control index on Realtek ALC88x
X-Git-Tag: accepted/tizen/common/20141203.182822~7926^2~24^2~7
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=7e59e097c09b82760bb0fe08b0fa2b704d76c3f4;p=platform%2Fkernel%2Flinux-arm64.git

ALSA: HDA: Fixup unnecessary volume control index on Realtek ALC88x

Without this change, a volume control named "Surround" or "Side" would
get an unnecessary index, causing it to be ignored by the vmaster and
PulseAudio.
