Message-Id: <1555048943-39589-1-git-send-email-wen.yang99@zte.com.cn> Date: Fri, 12 Apr 2019 14:02:18 +0800 From: Wen Yang <wen.yang99@....com.cn> To: linux-kernel@...r.kernel.org Cc: wang.yi59@....com.cn, Wen Yang <wen.yang99@....com.cn> Subject: [PATCH 0/5] fix leaked of_node references in drivers/pinctrl The call to of_get_cpu_node/of_find_compatible_node/of_parse_phandle... returns a node pointer with refcount incremented thus it must be explicitly decremented after the last usage. We developed a coccinelle SmPL to detect drivers/pinctrl code and found some issues. This patch series fixes those issues.
