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.
