drivers/char/n_gsm.c: add missing spin_unlock_irqrestore
Add a spin_unlock_irqrestore missing on the error path. Converting the
return to break leads to the spin_unlock_irqrestore at the end of the
function.
The semantic match that finds this problem is as follows:
(http://coccinelle.lip6.fr/)
// <smpl>
@@
expression E1;
@@
* spin_lock_irqsave(E1,...);
<+... when != E1
if (...) {
... when != E1
* return ...;
}
...+>
* spin_unlock_irqrestore(E1,...);
// </smpl>
