Currently there is no standardized method for USB drivers to handle
shutdown events. This patch simplifies running code on shutdown for USB
devices by adding a shutdown callback to usb_driver. It also implements the
new method to existing "USB Attached SCSI” driver that required shutdown

Is this good enough?

The subject looks fine to me. If you think it can be improved, suggestions shall be appreciated.
