Subject: [PATCH 3/3] regulator: mt6323: Add OF match table

From: Matthias Brugger <mbrugger@suse.com>

The binding documentation mentions that a compatible is required for the
MT6323 device node. But the driver does not provide a OF match table.
This way auto-loading is broken as the MFD driver that registers the
device has a .of_compatible set which makes the platform .uevent
callback report a OF modalias, but that's not in the module.
