** Description changed:

- This bug is for tracking purpose.
+ 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.
