This code is really really really broken. So much so that it's almost
impossible to fix with a simple patch, so just comment out the offending
registration with the kobject core, and mark the driver as broken.
The problem is that the code is trying to register a "raw" struct
device, which is not allowed. struct device is only for use within the
driver model. This is being done to try to use the firmware layer which
wants a struct device. To properly fix this, use something easy, like a
platform device, which is a struct device and can be used for this kind
of thing.
