From 7597fee389b18e5ed3c8bd58f0012674beb279ed Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 27 Mar 2006 01:17:02 -0800 Subject: [PATCH] [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.
