[PATCH] input: gameport: make gameport_bus const

From: Ricardo B. Marliere
Date: Sun Feb 04 2024 - 14:56:19 EST


Now that the driver core can properly handle constant struct bus_type,
move the gameport_bus variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
