Subject: [PATCH v2] ALSA: hda/realtek: Add quirk for mute LEDs on HP ENVY x360
 15-eu0xxx

The LED for the mic mute button is controlled by GPIO2.
The mute button LED is slightly more complex, it's controlled by two bits
in coeff 0x0b.

Changes since v1:
Rebased on 03b0563c2f35. I've got this laptop for almost two years now and
two days ago decided to dig into the issue with mute LEDs. What amazing timing
that someone else made the exact same fixup for a different model just hours
before I submit...
Renamed quirk to ..._LEDS to distinguish it from the similar quirk which
handles only one of the mute LEDs.
