Subject: IB/rxe: Use DEFINE_SPINLOCK() for spinlock
X-Git-Tag: v4.14-rc1~1791^2~16^5~11
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=4ac4707102d9ea1ffc9b5735891f6c5ee3d236e5;p=platform%2Fkernel%2Flinux-rpi3.git

IB/rxe: Use DEFINE_SPINLOCK() for spinlock

spinlock can be initialized automatically with DEFINE_SPINLOCK()
rather than explicitly calling spin_lock_init().
