Subject: [PATCH 0/3] fix leaked of_node references in drivers/media
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.
