Subject: linux-next: manual merge of the drm-intel tree with the
 drm-intel-fixes tree

Hi all,

Today's linux-next merge of the drm-intel tree got a conflict in:

  drivers/gpu/drm/i915/intel_display.c

between commit:

  76dc3769d7c3 ("drm/i915: Don't clobber the addfb2 ioctl params")

from the drm-intel-fixes tree and commit:

  dcb1394e74e3 ("drm/i915: On fb alloc failure, unref gem object where it gets refed")

from the drm-intel tree.

I fixed it up (see below) and can carry the fix as necessary (no action
is required).
