From: Bjorn Helgaas Date: Mon, 27 Mar 2006 09:17:02 +0000 (-0800) Subject: [PATCH] pnp: parport: adjust pnp_register_driver signature X-Git-Tag: v2.6.17-rc1~356 X-Git-Url: http://pilppa.com/gitweb/?a=commitdiff_plain;h=7597fee389b18e5ed3c8bd58f0012674beb279ed;p=linux-2.6-omap-h63xx.git [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.
