I am assuming the 4bit field was a mistake by orignal author. Using GENMASK,
BIT etc macro helps you to avoid those as one would look at datasheet and
say this is specfied as bit 5 thru 9, so let me say GENMASK(5, 0) rather
than a typo which missed 5th bit.

But ofcourse if the error was due to some other reason then this one doesnt
help.
