fs/ocfs2/dlm: Add missing spin_unlock
Add a spin_unlock missing on the error path. Unlock as in the other code that leads to the leave label. The semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression E1; @@ * spin_lock(E1,...); <+... when != E1 if (...) { ... when != E1 * return ...; } ...+> * spin_unlock(E1,...); // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Joel Becker <joel.becker@oracle.com>
