Subject: [PATCH v2] arm: mach-rockchip: (pm) Add missing of_node_put()
Date: Thu, 16 Jun 2022 10:17:13 +0800 [thread overview]
Message-ID: <20220616021713.3973472-1-windhl@126.com> (raw)
In rockchip_suspend_init(), of_find_matching_node_and_match() will
return a node pointer with refcount incremented. We should use
of_node_put() in fail path or when it is not used anymore.

changelog:
v2: (1) use real name for Sob (2) use goto-label patch style
v1: add of_node_put() for each return
