hsi: hsi_core: make hsi_bus_type const

rbmarliere · sre · commit a0e35a173a86 · 2024-02-06T16:08:46.000+01:00
Now that the driver core can properly handle constant struct bus_type, move the hsi_bus_type variable to be a constant structure as well, placing it into read-only memory which can not be modified at runtime.
