/*
* The of_device *was* a kind of "base class" that was a superset of
* struct device for use by devices attached to an OF node and probed
* using OF properties. However, the important bit of OF-style
* probing, namely the device node pointer, has been moved into the
* common struct device when CONFIG_OF is set to make OF-style probing
* available to all bus types. So now, just make of_device and
* platform_device equivalent so that current of_platform bus users
* can be transparently migrated over to using the platform bus.
*
* This line will go away once all references to of_device are removed
* from the kernel.
