What commit ID are you looking at?  I only see this:

	commit def8867a8d2a9f474262dd46179770845a420d51
	Author: Lennert Buytenhek <buytenh@wantstofly.org>
	Date:   Tue Sep 23 02:35:17 2008 +0200

	    phylib: rename mii_bus::dev to mii_bus::parent
	    
	    In preparation of giving mii_bus objects a device tree presence of
	    their own, rename struct mii_bus's ->dev argument to ->parent, since
	    having a 'struct device *dev' that points to our parent device
	    conflicts with introducing a 'struct device dev' representing our own
	    device.

Thanks!

Yeah, sorry for not reporting that separately.  (I'm not sure if it's
worth fixing separately, since deinit probably doesn't happen very
often.)


cheers,
