[PATCH] pnp: parport: adjust pnp_register_driver signature
Remove the assumption that pnp_register_driver() returns the number of devices
claimed.
parport_pc_init() does nothing with "count", so remove it. Then nobody uses
the return value of parport_pc_find_ports(), so make it void. Finally, update
pnp_register_driver() usage.
