Subject: locking/atomics/arm64, arm64/bitops: Include <asm-generic/bitops/ext2-atomic-setbit.h>
X-Git-Tag: v4.19~479^2~40
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=356c6fe7d80c678cf77aede0f95291dfd5ed2ef2;p=platform%2Fkernel%2Flinux-rpi.git

locking/atomics/arm64, arm64/bitops: Include <asm-generic/bitops/ext2-atomic-setbit.h>

<asm-generic/bitops/ext2-atomic-setbit.h> provides the ext2 atomic bitop
definitions, so we don't need to define our own.
