fs/xfs/quota: Add missing mutex_unlock
Add a mutex_unlock missing on the error path. The use of this lock is balanced elsewhere in the file. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression E1; @@ * mutex_lock(E1,...); <+... when != E1 if (...) { ... when != E1 * return ...; } ...+> * mutex_unlock(E1,...); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Alex Elder <aelder@sgi.com>
