[PATCH] phy: marvell: phy-armada38x-comphy: Add of_node_put() before return

From: Nishka Dasgupta
Date: Tue Jul 23 2019 - 06:49:39 EST


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. Hence add an of_node_put before the
return.
Issue found with Coccinelle.
