[PATCH] pnp: PNP: adjust pnp_register_driver signature
Remove the assumption that pnp_register_driver() returns the number of devices
claimed. Returning the count is unreliable because devices may be hot-plugged
in the future.
This changes the convention to "zero for success, or a negative error value,"
which matches pci_register_driver(), acpi_bus_register_driver(), and
platform_driver_register().
