From f162b9d58273a9a5747211133c8ccb2de5cf5ff2 Mon Sep 17 00:00:00 2001 From: Andy Fleming Date: Fri, 2 May 2008 13:00:30 -0500 Subject: gianfar: Fix a locking bug in gianfar's sysfs code During sparse cleanup, found a locking bug. Some of the sysfs functions were acquiring a lock, and then returning in the event of an error. We rearrange the code so that the lock is released in error conditions, too.
