From 2dbfc6525046122f35bf5c244c22551fb5566761 Mon Sep 17 00:00:00 2001 From: Nishka Dasgupta Date: Tue, 9 Jul 2019 14:26:40 -0300 Subject: [PATCH] media: i2c: tvp5150: Add of_node_put() before goto 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 in four places. Issue found with Coccinelle.
