[PATCH 2/3] mmc: core: make mmc_bus_type const

From: Ricardo B. Marliere
Date: Sat Feb 03 2024 - 14:02:24 EST


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