[PATCH] memory: ti-aemif: Add of_node_put() before goto

From: Nishka Dasgupta
Date: Tue Jul 09 2019 - 13:30:40 EST


Each iteration of for_each_available_child_of_node puts the previous
node, but in the case of a goto from the middle of the loop, there is
no put, thus causing a memory leak. Hence add an of_node_put before the
goto.
Issue found with Coccinelle.
