On a Dell laptop, there is no global adcs for all input devices, so
the input devices use the different adc, as a result, dyn_adc_switch
is set to true.
In this situation, it is safe to control the micmute led according to
user's choice of muting/unmuting the current input device, since only
current input device path is active, while other input device paths
are inactive and powered down.

The mic mute led on dell laptops is controlled by the wmi driver.
Followed this part being merged to the kernel, we add the mic mute led
hook in the hda driver.
