spmi: make spmi_bus_type const

rbmarliere · gregkh · commit b928d357576a · 2024-05-08T19:46:10.000+01:00
Now that the driver core can properly handle constant struct bus_type, move the spmi_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
