To: Greg KH, axboe; +Cc: lkml
In the near future, the driver core is going to not allow direct access
to the driver_data pointer in struct device. Instead, the functions
dev_get_drvdata() and dev_set_drvdata() should be used. These functions
have been around since the beginning, so are backwards compatible with
all older kernel versions.

Changelog was from Greg. Please review. In particular, is this required?
- dev->core.driver_data = NULL;
+ dev_set_drvdata(&dev->core, NULL);

As this involves ps3_system_bus_devices, they should use
ps3_system_bus_[gs]et_driver_data(), too?
