Merge branch 'upstream' into bugfix-video
Update bugfix-video branch to 2.5-rc1 so I don't have to again resolve the conflict in these patches vs. upstream. Conflicts: drivers/gpu/drm/gma500/psb_drv.c text conflict: add comment vs delete neighboring line keep just this: /* igd_opregion_init(&dev_priv->opregion_dev); */ /* acpi_video_register(); */ Signed-off-by: Len Brown <len.brown@intel.com>
