From 01115e7d41c4eaeffa064d818b4abbd3efa94f80 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 28 Apr 2008 16:34:38 -0600 Subject: [PATCH] ISAPNP: fold isapnp_read_resources() back into isapnp_get_resources() isapnp_get_resources() does very little besides call isapnp_read_resources(), so just fold them back together.
