From c153f45f9b7e30289157bba3ff5682291df16caa Mon Sep 17 00:00:00 2001 From: Eric Anholt Date: Mon, 3 Sep 2007 12:06:45 +1000 Subject: drm: Replace DRM_IOCTL_ARGS with (dev, data, file_priv) and remove DRM_DEVICE. The data is now in kernel space, copied in/out as appropriate according to t This results in DRM_COPY_{TO,FROM}_USER going away, and error paths to deal with those failures. This also means that XFree86 4.2.0 support for i810 DR is lost.
