From 02d83b5da3efa3c278ce87db2637f3dd6837166d Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 28 Apr 2008 16:34:28 -0600 Subject: PNP: make pnp_resource_table private to PNP core There are no remaining references to the PNP_MAX_* constants or the pnp_resource_table structure outside of the PNP core. Make them private to the PNP core.
