We can argue if dt-binding patches should have a fixes tag at all. Given the 
fact that there are so many warnings still around, I don't see any value add to 
backport these to stable kernel.

That said, this is defenitely no fix, as it's only a code clean-up. No warning, 
no bug, no functional error fixed here :)

Please sort compatibles, that will allow for easier reading once we add more to 
the file.
