Subject: [PATCH 16/37] binder: remove dead code in binder_get_ref_for_node
Date: Thu, 29 Jun 2017 12:01:50 -0700	[thread overview]
Message-ID: <20170629190211.16927-17-tkjos@google.com> (raw)
In-Reply-To: <20170629190211.16927-1-tkjos@google.com>

node is always non-NULL in binder_get_ref_for_node so the
conditional and else clause are not needed
