Merge branch 'drm-fixes' of git://people.freedesktop.org/~airlied/linux 

Pull drm fixes from Dave Airlie:
 "radeon, i915 and nouveau fixes, all fixes for regressions or black
  screens, or possible oopses"

* 'drm-fixes' of git://people.freedesktop.org/~airlied/linux:
  drm/radeon: lower the ref * post PLL maximum
  drm/radeon: check that we have a clock before PLL setup
  drm/radeon: drm/radeon: add missing radeon_semaphore_free to error path
  drm/radeon: Fix num_banks calculation for SI
  agp: info leak in agpioc_info_wrap()
  drm/gm107/gr: bump attrib cb size quite a bit
  drm/nouveau: fix another lock unbalance in nouveau_crtc_page_flip
  drm/nouveau/bios: fix shadowing from PROM on big-endian systems
  drm/nouveau/acpi: allow non-optimus setups to load vbios from acpi
  drm/radeon/dp: check for errors in dpcd reads
  drm/radeon: avoid high jitter with small frac divs
  drm/radeon: check buffer relocation offset
  drm/radeon: use pflip irq on R600+ v2
  drm/radeon/uvd: use lower clocks on old UVD to boot v2
  drm/i915: don't try DP_LINK_BW_5_4 on HSW ULX
  drm/i915: Sanitize the enable_ppgtt module option once
  drm/i915: Break encoder->crtc link separately in intel_sanitize_crtc()
