+Subject: ALSA: hda/realtek - Fixup mute led on HP Spectre x360
+
+From: Tom Briden <tom@decompile.me.uk>
+
+[ 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.
