Series drivers: mmc: struct bus_type cleanup | expand

Commit Message

Ricardo B. Marliere Feb. 3, 2024, 7:02 p.m. UTC 
Now that the driver core can properly handle constant struct bus_type,
move the mmc_rpmb_bus_type variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
