When using platform_driver_register(), the tables cannot be __init, as that
would cause a section type mismatch. Remember, the driver core handles
platform devices appearing later, so .probe() should continue to be available.
Note: in theory it should be possible to compile the CPG/MSSR driver as a
module, and have the module in your initramfs. But I don't think anyone
really wants to do that?

I agree. But if there's an unfixed bug somewhere else, we cannot introduce
regressions (for already supported SoCs).

Me too.
