Subject: ucm2: Add setting LED Mode in SetLED macro
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=2e090676c9a46f39c8ce880b59147df2cad828bc;p=alsa-ucm-conf.git

ucm2: Add setting LED Mode in SetLED macro

Add 'Mode' argument to SetLED macro in order to allow setting a
different LED mode. This will allow mute switches with inverted
values to control the LEDs with 'follow-route' option instead of
default 'follow-mute'.

The Mode argument is optional.

Closes: https://github.com/alsa-project/alsa-ucm-conf/pull/637
