Subject: [PATCH 1/1] pwm: core: use bitops's BIT macro

Checkpatch warns about not using the BIT() macro. Replace 1 << bit with
BIT().

Hi Thierry,

I submitted this patch a year ago and you said you didn't much care for it.
After a year however, have you changed your mind? I notice it's becoming
mandatory in more and more subsystems. Checkpatch is unhappy about it and
isn't it likely to be mandatory throughout the entire kernel at some point?

If you still think it should be omitted however, feel free to /dev/null this
patch :)

Olliver
