Subject: locking/lockdep: Remove unnecessary DEBUG_LOCKS_WARN_ON()
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=dd471efe345bf6f9e1206f6c629ca3e80eb43523;p=linux.git

locking/lockdep: Remove unnecessary DEBUG_LOCKS_WARN_ON()

DEBUG_LOCKS_WARN_ON() will turn off debug_locks and
makes print_unlock_imbalance_bug() return directly.

Remove a redundant whitespace.
