Subject: [PATCH] mtd: rawnand: vf610_nfc: Add of_node_put() before goto
Date: Tue,  9 Jul 2019 22:38:37 +0530
Message-ID: <20190709170837.13315-1-nishkadg.linux@gmail.com> (raw)

Each iteration of for_each_available_child_of_node puts the previous
node, but in the case of a goto from the middle of the loop, there is no
put, thus causing a memory leak. Hence add an of_node_put before the
goto.
Issue found with Coccinelle.
