I think I will just start rejecting all of thes "missing
MODULE_DEVICE_TABLE()" patches as they make no sense at all.

If the driver authors had wanted these MODULE_DEVICE_TABLES added, they
would have done so.  That means they were not using dynamically loaded
modules because usually, the module is built in, OR it doesn't matter.

So please, only add this if you have a system that needs them, do not
add them just based on a rule you have generated by a tool, as that is
pointless.

thanks,
