From 4ab55d8d4f7b910c4c60e0f8ff70d0dfdd484f02 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 28 Apr 2008 16:34:06 -0600 Subject: [PATCH] PNP: remove more pnp_resource_table arguments Stop passing around struct pnp_resource_table pointers. In most cases, the caller doesn't need to know how the resources are stored inside the struct pnp_dev.
