From 3cab7fd964916a5474dcaeb23b6723fbfb34cc66 Mon Sep 17 00:00:00 2001 From: Matthew Garrett Date: Wed, 7 Jan 2009 18:08:54 -0800 Subject: [PATCH] dcdbas: export functionality for use in other drivers The dcdbas code allows calls to be made into the firmware on Dell systems. Exporting this to other drivers allows them to implement Dell-specific functionality in a safe way.
