Subject: [PATCH] clk: cdce925: release child device nodes
Date: Wed, 22 Aug 2018 00:05:32 +0300	[thread overview]
Message-ID: <1534885532-26558-1-git-send-email-khoroshilov@ispras.ru> (raw)

of_get_child_by_name() returns device node with refcount incremented,
but there is no decrement in cdce925_probe(). The patch adds one.

Found by Linux Driver Verification project (linuxtesting.org).
