Subject: [PATCH] bus: qcom-ebi2: Add of_node_put() before return
Date: Tue, 23 Jul 2019 13:35:52 +0530
Message-ID: <20190723080552.7588-1-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. Add an of_node_put before the
return.
Issue found with Coccinelle.
