Subject: mips: txx9: make txx9_sramc_subsys const
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=1003a1adf493074bf7ba2d8075d87aa0ae73f69b;p=linux.git

mips: txx9: make txx9_sramc_subsys const

Now that the driver core can properly handle constant struct bus_type,
move the txx9_sramc_subsys variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
