Subject: [PATCH] phy: marvell: phy-mvebu-a3700-comphy: Add of_node_put() before return
Date: Tue, 23 Jul 2019 16:21:08 +0530 [thread overview]
Message-ID: <20190723105108.8306-1-nishkadg.linux@gmail.com> (raw)
Each iteration of for_each_available_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 in two places.
Issue found with Coccinelle.
