From 0a977f15469457d9a19eed992caf71995c674064 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 28 Apr 2008 16:34:31 -0600 Subject: PNP: add pnp_get_pnp_resource() In some places, we need to get the struct pnp_resource, not just the struct resource, because ISAPNP needs to store the register index in the pnp_resource. I don't like pnp_get_pnp_resource() and hope that it is temporary, but we need it for a little while.
