Subject: [PATCH 0/3] fix leaked of_node references in drivers/media
Date: Fri, 28 Jun 2019 11:01:13 +0800	[thread overview]
Message-ID: <1561690876-20977-1-git-send-email-wen.yang99@zte.com.cn> (raw)

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/media/ code and
found some issues.
This patch series fixes those issues.
