[PATCH 09/13] ALSA: hda/realtek: Use the new vmaster mute LED helper

Thu Jun 18 13:08:38 CEST 2020
Convert the mute LED handling in Realtek codec to the new vmaster mute
helper. A point to be cautiously handled is that the value passed to
the callback is inverted; the vmaster passes "enabled" (0 = mute),
while LED classdev passes "brightness" (1 = mute).
The code in Thinkpad helper is also converted. In that case, just
call the new function and remove the open-code.
