Are you sure this line ^ should be dropped ?
Shouldn't the bitfield be cleared first and modified second?
Well, I had in my mind that this function is called upon probe with clk_dif_sr
being cleared anyway, so this does essentially nothing. And the DIF bit is set
unconditionally, so what is the point of masking it before?
Good point, but then, what's the point of ORRing either ? Just do a
plain assignment.
