Merge tag 'drm-intel-next-fixes-2014-12-30' of git://anongit.freedesktop.org/drm-intel into linus
I've had these since before -rc1, but they missed my last pull request. Real bug fixes and mostly cc: stable material. * tag 'drm-intel-next-fixes-2014-12-30' of git://anongit.freedesktop.org/drm-intel: drm/i915: add missing rpm ref to i915_gem_pwrite_ioctl Revert "drm/i915: Preserve VGACNTR bits from the BIOS" drm/i915: Don't call intel_prepare_page_flip() multiple times on gen2-4 drm/i915: Kill check_power_well() calls
