Subject: [net-next-2.6 PATCH] can: rename can_try_module_get to can_get_proto
Date: Wed, 4 May 2011 06:42:04 +0200 [thread overview]
Message-ID: <20110504044204.GD278@e-circ.dyndns.org> (raw)
can: rename can_try_module_get to can_get_proto
can_try_module_get does return a struct can_proto.
The name explains what is done in so much detail that a caller
may not notice that a struct can_proto is locked/unlocked.
