  drm: fixup some of the ioctl function exit paths
  drm: the drm really should call pci_set_master..
  i915: Add chipset id for Intel Integrated Graphics Device
  drm: cleanup DRM_DEBUG() parameters
  drm/i915: add support for E7221 chipset
  drm: don't cast a pointer to pointer of list_head
  mga_dma: return 'err' not just zero from mga_do_cleanup_dma()
  drm: add _DRM_DRIVER flag, and re-order unload.
  drm: enable udev node creation
  drm: Make DRM_IOCTL_GET_CLIENT return EINVAL when it can't find client #idx.
  drm: move drm_mem_init to proper place in startup sequence
  drm: call driver load function after initialising AGP
  drm: Fix ioc32 compat layer
  drm: fd.o bug #11895: Only add the AGP base to map offset if the caller didn't.
  i915: add suspend/resume support
  drm: update DRM sysfs support
  drm: Initialize the AGP structure's base address at init rather than enable.
  drm: move two function extern into the correct block
