[PATCH] irda: Fix RCU lock pairing on error path

From: Josh Triplett
Date: Wed Jun 28 2006 - 20:55:13 EST


irlan_client_discovery_indication calls rcu_read_lock and rcu_read_unlock, but
returns without unlocking in an error case. Fix that by replacing the return
with a goto so that the rcu_read_unlock always gets executed.
