PowerCap: Fix an error code in powercap_register_zone()
In the current code we accidentally return the successful result from idr_alloc() instead of a negative error pointer. The caller is looking for an error pointer and so it treats the returned value as a valid pointer. This one might be a bit serious because if it lets people get around the kernel's protection for remapping NULL. I'm not sure.
