Subject: counter: make counter_bus_type const
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6b0828ca8bd18315647511dfe731101b6a59de2b;p=linux.git

counter: make counter_bus_type const

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