From mboxrd@z Thu Jan 1 00:00:00 1970 From: Bjorn Helgaas Subject: [patch 26/54] PNP: factor pnp_init_resource_table() and pnp_clean_resource_table() Date: Fri, 25 Apr 2008 12:38:33 -0600 Message-ID: <20080425183929.396758295@ldl.fc.hp.com> References: <20080425183807.366134771@ldl.fc.hp.com> Return-path: Received: from g1t0028.austin.hp.com ([15.216.28.35]:9932 "EHLO g1t0028.austin.hp.com" rhost-flags-OK-OK-OK-OK) by vger.kernel.org with ESMTP id S1764416AbYDYSkF (ORCPT ); Fri, 25 Apr 2008 14:40:05 -0400 Content-Disposition: inline; filename=pnp-factor-init-resources Sender: linux-acpi-owner@vger.kernel.org List-Id: linux-acpi@vger.kernel.org To: Len Brown Cc: linux-acpi@vger.kernel.org, linux-kernel@vger.kernel.org, Adam Belay , Adam M Belay , Li Shaohua , Matthieu Castet , Thomas Renninger , Rene Herman , Jaroslav Kysela , Andrew Morton Move the common part of pnp_init_resource_table() and pnp_clean_resource_table() into a new pnp_init_resource(). This reduces a little code duplication and will be useful later to initialize an individual resource.
