Subject: mfd: mt6397: Add platform device ID table
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=e1d9a10918396ae26dd5181d454c793ff17c9ded;p=openwrt%2Fstaging%2Fblogic.git

mfd: mt6397: Add platform device ID table

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.
