The Documentation/devicetree/bindings/regulator/mt6397-regulator.txt doc
mentions that a compatible "mediatek,mt6397-regulator" is required for
the MT6397 device node but the driver doesn't provide a OF match table so
the platform bus .match fallbacks to match using the driver name instead.
This also means that module auto-loading is broken for this driver since
the MFD driver that register the device, has a .of_compatible set so the
platform .uevent callback reports a OF modalias that's not in the module.

The platform bus_type .match callback attempts to match the platform device
name with an entry on the .id_table if provided and fallbacks to match with
the driver's name if a table is not provided.
Using a platform device ID to match is more explicit, allows the driver to
support more than one device and also the MODULE_DEVICE_TABLE macro can be
used to export the module aliases information instead of the MODULE_ALIAS.
