mfd: Rohm PMICs: Use platform_device_id to match MFD sub-devices
Thanks to Stephen Boyd I today learned we can use platform_device_id to do device and module matching for MFD sub-devices! Do device matching using the platform_device_id instead of using explicit module_aliases to load modules and custom parent-data field to do module loading and sub-device matching.
