Subject: [PATCH AUTOSEL 4.9 04/45] pinctrl: rockchip: fix leaked of_node references
Date: Fri, 19 Jul 2019 00:12:23 -0400	[thread overview]
Message-ID: <20190719041304.18849-4-sashal@kernel.org> (raw)
In-Reply-To: <20190719041304.18849-1-sashal@kernel.org>

From: Wen Yang <wen.yang99@zte.com.cn>

[ 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.
