From: Nishka Dasgupta Date: Sun, 4 Aug 2019 15:51:54 +0000 (+0530) Subject: pinctrl: nomadik: abx500: Add of_node_put() before return X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=f452444709c07ea5d126e9f312f602ac9c5e34fd;p=linux.git pinctrl: nomadik: abx500: Add of_node_put() before return 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.
