Subject: [patch 50/54] ISAPNP: fold isapnp_read_resources() back into isapnp_get_resources()
Content-Disposition: inline; filename=isapnp-fold-isapnp_read_resources
Sender: linux-kernel-owner@vger.kernel.org
List-ID: <linux-kernel.vger.kernel.org>
X-Mailing-List: linux-kernel@vger.kernel.org

isapnp_get_resources() does very little besides call
isapnp_read_resources(), so just fold them back together.

Based on a patch by Rene Herman <rene.herman@gmail.com>
