Subject: [PATCH] mtd: rawnand: meson: Add of_node_put() before return
Date: Tue,  9 Jul 2019 22:46:40 +0530	[thread overview]
Message-ID: <20190709171640.13511-1-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.
