Subject: clocksource: Make clocksource_subsys const
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=2bc7fc24f9a85cb6b7335354b2733615727689f6;p=linux.git

clocksource: Make clocksource_subsys const

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