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

From: Greg Kroah-Hartman
Date: Wed Jul 10 2024 - 03:34:25 EST


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.
