Subject: [PATCH 3.18 19/24] mdio-sun4i: Fix a memory leak
Date: Fri,  2 Mar 2018 09:51:16 +0100	[thread overview]
Message-ID: <20180302084240.092972403@linuxfoundation.org> (raw)
In-Reply-To: <20180302084239.157503766@linuxfoundation.org>

3.18-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Christophe JAILLET <christophe.jaillet@wanadoo.fr>


[ Upstream commit 56c0290202ab94a2f2780c449395d4ae8495fab4 ]

If the probing of the regulator is deferred, the memory allocated by
'mdiobus_alloc_size()' will be leaking.
It should be freed before the next call to 'sun4i_mdio_probe()' which will
reallocate it.

Fixes: 4bdcb1dd9feb ("net: Add MDIO bus driver for the Allwinner EMAC")
