Subject: [PATCH] i3c: master: Add of_node_put() before return
Date: Tue, 23 Jul 2019 16:07:25 +0530 [thread overview]
Message-ID: <20190723103725.7950-1-nishkadg.linux@gmail.com> (raw)
Each iteration of for_each_available_childe_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.
