Subject: [PATCH] clk: socfpga: fix refcount leak
Date: Wed, 26 Dec 2018 08:29:02 -0500 [thread overview]
Message-ID: <20181226132902.4807-1-tiny.windzz@gmail.com> (raw)
The of_find_compatible_node() returns a node pointer with refcount
incremented, but there is the lack of use of the of_node_put() when
done. Add the missing of_node_put() to release the refcount.
