+Subject: [PATCH] Pull DRM dependent code only when the DRM compositor is
+ enabled
+
+The <xf86drm.h> header and the drm*() functions may not be available
+at all when the DRM compositor is not enabled, so they should not be
+used. Fixes build failures when building the fbdev compositor on
+systems where DRM is not available.
