Public bug reported:
Since this patch cced to stable and only oem project needs this
fix urgently, only send the sru to oem-5.10 kernel, other ubuntu
kernels will merge this patch with stable update.
[Impact]
On a lenovo machine, the micmute led init state is not correct, after
freshly installing the os and boot up, the mic is not muted, but the
micmute led is on.
[Fix]
backport a patch from upstream.
[Test]
Booting the system with patched kernel, the micmute led
init state is correct. If mic is mute, the led is on, if
the mic is not mute, the led is off.
[Where problems could occur]
This could introduce the micmute led wrong init state on other
machines, we tested this patch on many lenovo machines, no regression
found so far.
