Subject: s390/time: make stp_subsys const
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=6695d792246eb69c77e5952a0b85c8684950ed71;p=linux.git

s390/time: make stp_subsys const

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