[PATCH 8/12] drivers/scsi/lpfc: Unlock the lock that was locked

From: Julia Lawall
Date: Mon Mar 29 2010 - 11:35:50 EST


From: Julia Lawall <julia@xxxxxxx>

The lock taken was in the ct_ev_lock field, not the hbalock field.

A simplified version of the semantic patch that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

// <smpl>
@r exists@
expression E1;
identifier f;
@@

f (...) { <+...
* spin_lock_irqsave (E1,...);
... when != E1
* return ...;
...+> }
// </smpl>
