[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().
