[PATCH 2/2] mips: txx9: make txx9_sramc_subsys const
Posted by Ricardo B. Marliere 2 years ago
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.
