Bug description:
[Impact]
Error messge is issued during boot up,
"platform::micmute: Setting an LED's brightness failed (-19)",
but there's no micmute led on the machine.
[Fix]
Get the related tokens of SMBIOS, GLOBAL_MIC_MUTE_DISABLE/ENABLE.
If one of two tokens doesn't exist, don't register platform::micmute.
After that, you wouldn't see the platform::micmute in /sys/class/leds/,
and the error message wouldn't see in dmesg.
[test]
With the patch, if GLOBAL_MIC_MUTE_DISABLE/ENABLE don't exist, the error
message
wouldn't be triggered and can't find platform::micmute in /sys/class/leds
[Regression Potential]
low, just avoid to register if device isn't presented.
