X-Git-Tag: firefly_0821_release~3680^2~3345^2~22^2~1

driver-core: Allow additional parameters for module_driver

Allow module_driver take additional parameters which will be passed to the
register and unregister function calls. This allows it to be used in cases
where additional parameters are required (e.g. usb_serial_register_drivers).
