[SRU] [F/G/Unstable/OEM-5.10] [PATCH 0/1] Enable mute and micmute LED on HP EliteBook 850 G7

[Kai-Heng Feng]

BugLink: https://bugs.launchpad.net/bugs/1910102

[Impact]
Mute and micmute LED on HP EliteBook 850 G7 don't reflect the mute
status.

[Fix]
Apply an HDA quirk to let HP EliteBook 850 G7 use codec GPIO to control
LED.

[Test]
With the patch applied, both mute and micmute LED can be lit when audio
output or input is muted, respectively.

[Where problems could occur]
This quirk is specific to one model. It's not likely to regress other
systems.

HP EliteBook 850 G7 uses the same GPIO pins as ALC285_FIXUP_HP_GPIO_LED
to enable mute and micmute LED. So apply the quirk to enable the LEDs.

Patch upstream now with same SHA1, linux-next can be dropped from cherry picked
line when applying.
