Public bug reported:
[Impact]
HDMI/DP audio isn't working on Dell's USB-C dock.
[Fix]
Leave Maud/Naud as is, since the hardware programmed the right value
already.
[Test]
HDMI/DP audio always comes out from the USB-C dock after the fix is
applied.
[Where problems could occur]
The commits affects _all_ HDMI/DP audio that connects to Intel GFX. So
all of them are affected hence the regression risk isn't low.
Therefore let the commit sits in OEM kernel first. Stable kernels can
pull in this fix after it's getting thoroughly tested.
