      drm/i915: Add GEN7_PCODE_MIN_FREQ_TABLE_GT_RATIO_OUT_OF_RANGE to SNB · fc2780b6
      Chris Wilson authored
      According to the CI test machines, SNB also uses the
      GEN7_PCODE_MIN_FREQ_TABLE_GT_RATIO_OUT_OF_RANGE value to report a bad
      GEN6_PCODE_MIN_FREQ_TABLE request.

      drm/imx: Add active plane reconfiguration support · c6c1f9bc
      Liu Ying authored
      We don't support configuring active plane on-the-fly for imx-drm.
      The relevant CRTC should be disabled before the plane configuration.
      Of course, the plane itself should be disabled as well.
      This patch adds active plane reconfiguration support by forcing CRTC
      mode change and disabling-enabling plane in plane's ->atomic_update
      callback.

      drm/i915/dvo: Remove dangling call to drm_encoder_cleanup() · 8a07fed4

      If we hit the error path, we have never called drm_encoder_init() and so
      have nothing to cleanup. Doing so hits a null dereference:
