The automatic fix changed from
GENMASK(3, 27) to
GENMASK(27, 3)
I reviewd again the code to check how it worked so far and saw that it
should have been
GENMASK(28, 27) - this is a different value than 9bdd7bb3a844
For our fortune this wrong value didn't effect the our final write to
the register.
But still this should be fixed.
