Subject: [PATCH v3] cpuidle: big.LITTLE: add of_node_put()
Date: Tue, 20 Nov 2018 11:14:51 -0500 [thread overview]
Message-ID: <20181120161451.21149-1-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.
bl_idle_init() doesn't do that, so fix it.
