[PATCH] zorro: make match function take a const pointer

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

In commit d69d80484598 ("driver core: have match() callback in struct bus_type
take a const *"), the match callback for busses was changed to take a const
pointer to struct device_driver.  Unfortunatly I missed fixing up the zorro
code, and was only noticed after-the-fact by the kernel test robot.  Resolve
this issue by properly changing the zorro_bus_match() function.
