A nit and a question follow.

This states the license is GPL v2.

According to include/linux/module.h this sates the license is GPL v2 or
later. So I think that either the comment at the top of this file or the
ident used in the MODULE_LICENSE() macro needs to change.

As far as I understand it, this alias is only useful if there's a
corresponding struct platform_device, somewhere. Ie, this alias needs a
platform_device that will fire of a "MODALIAS=platform:i2c-mux-reg"
uevent when it's created. (I don't know exactly how all that works, so
I'm handwaving quite a bit here.) That would be platform_device with a
"i2c-mux-reg" name.

Did I get this right? Because then I think this MODULE_ALIAS() isn't
needed, as I couldn't find such a corresponding platform_device.

Thanks,
