X-Git-Tag: MMI-PSA29.97-13-9~18103^2~124^2~69^2~1
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=f2b1c9f031d6b7604f861223f9e7024e6597b201;p=GitHub%2FMotorolaMobilityLLC%2Fkernel-slsi.git

ALSA: hda - Auto-mute smart51 surround pins for VIA codecs

When smart51 mode is enabled, auto-mute these surround outputs
as well as the primary line-out.  Also this patch includes minor
clean-ups.
