Subject: [PATCH v2] ata: pata_macio: add of_node_put()
Date: Thu, 22 Nov 2018 07:39:24 -0500	[thread overview]
Message-ID: <20181122123924.24438-1-tiny.windzz@gmail.com> (raw)

of_find_node_by_path() acquires a reference to the node
returned by it and that reference needs to be dropped by its caller.
This place doesn't do that, so fix it.
