Subject: [PATCH AUTOSEL 4.4 07/15] net: mv643xx_eth: disable clk on error path in mv643xx_eth_shared_probe()
Date: Wed, 13 Mar 2019 15:17:53 -0400	[thread overview]
Message-ID: <20190313191806.160547-7-sashal@kernel.org> (raw)
In-Reply-To: <20190313191806.160547-1-sashal@kernel.org>

From: Alexey Khoroshilov <khoroshilov@ispras.ru>

[ Upstream commit e928b5d6b75e239feb9c6d5488974b6646a0ebc8 ]

If mv643xx_eth_shared_of_probe() fails, mv643xx_eth_shared_probe()
leaves clk enabled.
