Subject: [PATCH] drivers: of: check input parameter name for __of_find_property
Date: Fri, 11 Sep 2015 21:44:03 +0800	[thread overview]
Message-ID: <1441979043-19694-1-git-send-email-van.freenix@gmail.com> (raw)

Check input parameter 'name' for __of_find_property. If name is NULL,
of_prop_cmp->strcasecmp may trigger panic.
