Subject: [PATCH v2 08/15] ARM: shmobile: fix a leaked reference by adding missing of_node_put
Date: Tue, 5 Mar 2019 19:33:59 +0800 [thread overview]
Message-ID: <1551785646-46173-8-git-send-email-wen.yang99@zte.com.cn> (raw)
In-Reply-To: <1551785646-46173-1-git-send-email-wen.yang99@zte.com.cn>
The call to of_get_next_child returns a node pointer with refcount
incremented thus it must be explicitly decremented after the last
usage.
Detected by coccinelle with the following warnings:
./arch/arm/mach-shmobile/pm-rcar-gen2.c:77:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 66, but without a corresponding object release within this function.
./arch/arm/mach-shmobile/pm-rcar-gen2.c:85:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 66, but without a corresponding object release within this function.
./arch/arm/mach-shmobile/pm-rcar-gen2.c:90:2-8: ERROR: missing of_node_put; acquired a node pointer with refcount incremented on line 66, but without a corresponding object release within this function.
