So interestingly MDA is a valid PNP ID. But an old one from 1997 for
Media4 Inc. 

Let's hope they never used that device number in a way that will bite us.

Applied to the togreg branch of iio.git and pushed out as testing for 0-day
to play with it.

Note that if anyone has a path to Chuwi to educate them on how to do
ACPI ids correctly then feel free to pass it on!

The MXC ones are also invalid btw - in that case there is no such PNP
ID unless it's been very recently granted which seems unlikely.
