You should not need MODULE_ALIAS() in normal cases. If you need it,
usually it means your device ID table is wrong (e.g. misses either
entries or MODULE_DEVICE_TABLE()). MODULE_ALIAS() is not a substitute
for incomplete ID table.

This applies also to your other driver: pinctrl. Maybe to all your
drivers... Don't use MODULE_ALIAS() as substitute for missing tables.
