This series of patches removes 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. (Many devices don't support hot-plug, of course, but PNP in general does.) 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(). If drivers need to know the number of devices, they can count calls to their .probe() methods. This patch: Remove the assumption that pnp_register_driver() returns the number of devices claimed.
