[PATCH] mfd: mt6397: Add platform device ID table

From: Javier Martinez Canillas
Date: Tue Feb 09 2016 - 06:10:49 EST


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.
