Subject: device-dax: make dax_bus_type const
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=bc22374c96d959084bea1287cfc6ea0fd9ca4e40;p=linux.git

device-dax: make dax_bus_type const

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