Subject: ALSA: hda - Clean up multi-channel mixer name assignment in patch_realtek.c
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=6843ca16f5e381ae80fc563931f8c74bda9fa29a;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ALSA: hda - Clean up multi-channel mixer name assignment in patch_realtek.c

Change alc_get_line_out_pfx() in patch_realtek.c to provide the channel
specific name and assign the index so that each caller doesn't have to
set the channel name by itself.

Also, check the multi-io case with the primary hp-out; for the multi-io
channels, assign the channel name instead of "Headphone" with indices.
This makes the mixer names more intuitive and reduces confusion.
