Subject: [PATCH] pinctrl: nomadik: nomadik: Add of_node_put() before return
Date: Sun, 4 Aug 2019 21:21:17 +0530 [thread overview]
Message-ID: <20190804155117.4753-1-nishkadg.linux@gmail.com> (raw)
Each iteration of for_each_child_of_node puts the previous node, but in
the case of a return from the middle of the loop, there is no put, thus
causing a memory leak. Hence add an of_node_put before the return.
Issue found with Coccinelle.
