X-Git-Tag: v2.6.36-rc1~134
X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=e73790a57abc1320b3c3a94da43ae24359687d7c;p=pandora-kernel.git

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>
