Subject: [PATCH 0/9] PNP: adjust pnp_register_driver signature
Date: Thu, 2 Mar 2006 16:01:27 -0700 [thread overview]
Message-ID: <200603021601.27467.bjorn.helgaas@hp.com> (raw)
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.
