Subject: ALSA: HDA VIA: Modify vt1709_auto_create_multi_out_ctls.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4483a2f5907fa824bd6384c36fdcee9777cab1b9;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git

ALSA: HDA VIA: Modify vt1709_auto_create_multi_out_ctls.

Rewrite nid_vol/mute assignment for clearity, and check line connection
before adding control for it.
