Why don't you get rid of the global raw_devices array instead?

I suppose if you embed the struct cdev in raw_device_data and
register it during RAW_SETBIND separately for each raw device
instead of globally at raw_init time, you can support any number
of devices while making the code smaller and simpler. I suppose
you can even remove the raw_mutex then.
