The 1st patch reverts an already merged patch which makes less sense. (https://mailman.alsa-project.org/pipermail/alsa-devel/2020-January/161172.ht...)
The 3rd patch uses the function introduced from the 2nd patch to fix a deadlock issue. I wasn't aware of the deadlock issue because my test environment doesn't change the MUX. Could be manually tested by something like: `amixer -c1 cset name='LTENL Mux' 0`.
