From 43a9539fa9e780f16c0d1e4bc91a2701f1ce178f Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Fri, 8 Jul 2011 12:22:36 +0100 Subject: drm/i915: Only export the generic intel_disable_fbc() interface As the enable/disable routines will be gain additional complexity in future patches, it is necessary that all callers do not bypass the generic interface by calling into the chipset routines directly. to do this we make the chipset routines static, so there is no choice.
