[PATCH 4.14 146/185] ALSA: hda/realtek - Fixup mute led on HP Spectre x360

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Tom Briden <tom@xxxxxxxxxxxxxxx>

[ Upstream commit 7f783bd5e215a014a3c98df64bef24c2dc736def ]

This patch adds the mute LED control for HP Spectre x360 Kabylake
model.  The mute LED is controlled via VREF bits on NID 0x1b, so we
need a new fixup function.

Note that this doesn't fix the other issues like the missing speaker
output on the machine.  They will be addressed by later patches.
