Subject: ALSA: hda - show HBR(High Bit Rate) pin cap in procfs
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=b923528ed29dc2d12832f76b1b9e05848d9de853;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ALSA: hda - show HBR(High Bit Rate) pin cap in procfs

Note that the HBR capability only applies to HDMI pin.
