From 3fc72370186be2f9d4d6ef06d99e1caa5d92c564 Mon Sep 17 00:00:00 2001 From: Rasesh Mody Date: Wed, 21 Sep 2011 20:55:41 -0400 Subject: [PATCH] bna: PCI Probe Conf Lock Fix If register_netdev() fails now, then we call mutex_unlock(&bnad->conf_mutex); on the error path, but it's already unlocked. So we acquire the lock in error path which will be later unlocked after the cleanup. Reported-by: Dan Carpenter Signed-off-by: Rasesh Mody Signed-off-by: David S.
