From dde263880cda63fa1b9caecf5b188928f9a5a170 Mon Sep 17 00:00:00 2001 From: Rasmus Villemoes Date: Tue, 30 Oct 2018 15:05:07 -0700 Subject: [PATCH] linux/bitmap.h: fix type of nbits in bitmap_shift_right() [ Upstream commit d9873969fa8725dc6a5a21ab788c057fd8719751 ] Most other bitmap API, including the OOL version __bitmap_shift_right, take unsigned nbits. This was accidentally left out from 2fbad29917c98.
