Subject: Input: gameport - make gameport_bus const
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=d03f030115fe930de1222fef294730ba21b93045;p=linux.git

Input: gameport - make gameport_bus const

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.
