Subject: sof-hda-dsp: add workaround for speaker LED on MSI laptops
X-Git-Url: https://git.alsa-project.org/?a=commitdiff_plain;h=2132426f650fc1f43a9a967cfd3fa080b3f07e23;p=alsa-ucm-conf.git

sof-hda-dsp: add workaround for speaker LED on MSI laptops

Fixes: Master Playback Switch doesn't get attached to the Mute LED
       on these two platforms. This change adresses this issue.

Also fixes 0915b27a which accidentally broke dell workaround.

Closes: https://github.com/alsa-project/alsa-ucm-conf/pull/716
Fixes: 0915b27 ("ucm2: use new SetLED macro to hide the implementation details")
