From a1802c42950403657d07e64558eff612d550ce16 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 27 Jun 2008 16:57:04 -0600 Subject: PNP: make resource option structures private to PNP subsystem Nothing outside the PNP subsystem should need access to a device's resource options, so this patch moves the option structure declarations to a private header file.
