Subject: linux/bitmap.h: fix type of nbits in bitmap_shift_right()
Most other bitmap API, including the OOL version __bitmap_shift_right,
take unsigned nbits. This was accidentally left out from 2fbad29917c98.
Link: http://lkml.kernel.org/r/20180818131623.8755-5-linux@xxxxxxxxxxxxxxxxxx
Fixes: 2fbad29917c98 ("lib: bitmap: change bitmap_shift_right to take unsigned parameters")
