From 0ca248c6a6e52530d4c69f291e7923e0cb7fcb8f Mon Sep 17 00:00:00 2001 From: Wen Yang Date: Mon, 15 Apr 2019 14:24:02 +0800 Subject: [PATCH] pinctrl: rockchip: fix leaked of_node references [ Upstream commit 3c89c70634bb0b6f48512de873e7a45c7e1fbaa5 ] The call to of_parse_phandle returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. Detected by coccinelle with the following warnings: ./drivers/pinctrl/pinctrl-rockchip.c:3221:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 3196, but without a corresponding object release within this function. ./drivers/pinctrl/pinctrl-rockchip.c:3223:1-7: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 3196, but without a corresponding object release within this function.
