From 04eb94d526423ff082efce61f4f26b0369d0bfdd Mon Sep 17 00:00:00 2001 From: Nishka Dasgupta Date: Sun, 18 Aug 2019 10:39:01 +0100 Subject: [PATCH] slimbus: qcom-ngd-ctrl: Add of_node_put() before return 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 in two places. Issue found with Coccinelle.
