3.8.13.3 -stable review patch. If anyone has any objections, please let me know.
------------------ From: Peter Chen <[email protected]> commit f28c42c576b293b3a1daaed8ca2775ebc2fe5398 upstream. If the glue layer is removed first (core layer later), it deletes the phy device first, then the core device. But at core's removal, it still uses PHY's resources, it may cause kernel's oops. It is much like the problem Paul Zimmerman reported at: http://marc.info/?l=linux-usb&m=136547502011472&w=2. Besides, it is reasonable the PHY is deleted at last as the controller is the PHY's user.
