Merge tag 'drm-intel-fixes-2015-03-26' of git://anongit.freedesktop.org/drm-intel into drm-fixes
This should cover the final warnings in -rc5 with two more backports from our development branch (drm-intel-next-queued). They're the ones from Daniel and Damien, with references to the reports. This is on top of drm-fixes because of the dependency on the two earlier fixes not yet in Linus' tree. There's an additional regression fix from Chris. * tag 'drm-intel-fixes-2015-03-26' of git://anongit.freedesktop.org/drm-intel: drm/i915: Fixup legacy plane->crtc link for initial fb config drm/i915: Fix atomic state when reusing the firmware fb drm/i915: Keep ring->active_list and ring->requests_list consistent
