ADT746X: logical-bitwise & confusion in set_max_duty_at_crit()

[Roel Kluin]

Andrew, I think you may want this patch instead of the other
adt746x-logical-bitwise-confusion-in-set_max_duty_at_crit.patch

It includes suggested changes by Segher Boessenkool and I think this
version was tested by Darrick J. Wong
