Without this patch, the kernel will load generic codec driver, this will introduce
lots of problems like mute/micmute hotkey can't work.
We have an oem bug #1726245, the audio related hotkey can't work. The root cause
is the codec is not supported by current kernel driver.
Applying this patch and test the audio related hotkey.
Backport the uptream patch, the patch is written by Realtek engineers.
No, it does not change any existing functions.
