Subject: [PATCH] mtd: rawnand: ingenic: ingenic_nand: Add of_node_put() before return
Date: Tue,  9 Jul 2019 22:50:30 +0530
Message-ID: <> (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.
