Subject: media: media-devnode: make media_bus_type const
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=e248cde98470ca3d9449e2b744b11279681f8e18;p=linux.git

media: media-devnode: make media_bus_type const

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