    Merge tag 'v3.7-rc2' into drm-intel-next-queued

to solve conflicts blew up (either git or Daniel was trying to be too
clever for their own good; it's usually convenient to blame tools ;) and
caused the changes of

    drm/i915: use adjusted_mode instead of mode for checking the 6bpc force flag

in ironlake_crtc_mode_set() to be dropped.

Fix the call in ironlake_crtc_mode_set() again, and while at it, also fix
the new, copy-pasted haswell_crtc_mode_set() to use adjusted_mode.
