From: Ming Lei <tom.leiming@gmail.com>
This reverts commit ce21c7bcd796fc4f45d48781b7e85f493cc55ee5: We will remove platform_data field from struct device until all platform devices pass its specific data from platfom_device and all platform drivers use platform specific data passed by platform_device->platform_data. This kind of conversion will need a long time, for thousands of files is affected.
To make the conversion easily, we allow platform specific data passed by struct device or struct platform_device and platform driver may use it from struct device or struct platform_device.
As we really don't want to do this at all.
