Subject: [PATCH 0/3] fix leaked of_node references in drivers/firmware
Date: Wed, 17 Apr 2019 10:44:50 +0800 [thread overview]
Message-ID: <1555469093-35179-1-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/firmware code and
found some issues.
This patch series fixes those issues.
