Subject: [PATCH 7/9] drivers/net/phy/mdio-bitbang.c: Call mdiobus_unregister
 before mdiobus_free

[ Upstream commit aa731872f7d33dcb8b54dad0cfb82d4e4d195d7e ]

Based on commit b27393aecf66199f5ddad37c302d3e0cfadbe6c0

Calling mdiobus_free without calling mdiobus_unregister causes
BUG_ON(). This patch fixes the issue.

[...]

This introduces a regresssion, as mdiobus_unregister() is not safe to
call if the bus isn't registered.  Registration is controlled by the
drivers that use mdio-bitbang, and they should take care of
unregistration too - and most of them do.

This should be reverted in mainline and not applied to any stable
series.

Ok, I'll revert.

Greg, please toss it from your -stable queue as well.

Now tossed, thanks.
