Patch for ALSA hdea realtek: add quirk for HP Envy x360

Patch from Takashi Iwai of Linux Kernel team adding a quirk for HP Envy x360. I confirm the fix restore the functionality of LED mute button as tested on Kernel 5.2.8.

Comment 2 Luya Tshimbalanga 2019-08-13 23:42:24 UTC
Initial workaround was to create alsa.conf in /etc/modprobe.d/ with "options snd-hda-intel model=,hp-mute-led-mic3" parameter. The proposed patch from upstream removes that necessity.

Comment 3 Luya Tshimbalanga 2019-10-03 17:49:42 UTC
Closing this report as the fix is now available upstream.
