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. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
