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.
