My main concern is that it is going to be a tad harder to back port 
fixes made to this driver with such changes in place, so unfortunately 
it is usually a matter of either the initial version of the driver use 
BIT(), FIELD_{PREP,GET} and GENMASK, or the very few commits following 
the initial commit take care of that, and then it is all rosy for 
everyone, or else it may be complicated.

You are one of the active contributors to this driver, so ultimately you 
should decide.
