That means I've correctly figured out the purpose of this MODULE_ALIAS("platform:" stuff. Because it might actually be documented somewhere but I managed to not stumble on that documentation. With that out of the way: am I right in thinking there's currently no platform code that triggers that uevent for "MODALIAS=platform:i2c-mux-reg"? Because if there's no struct platform_device taking care of that I think this MODULE_ALIAS() should not be added, not yet.
