Good, I had a local patch that would pass bq24022_mach_info in
regulator_init_data->driver_data instead of platform_data.
Now that there is a possibility to pass platform_data, is there still
need for the driver_data field in regulator_init_data and for the
regulator_get_init_drvdata() function?
cheers
