[PATCH] pnp: mpu401: adjust pnp_register_driver signature
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.
