Subject: linux-next: build failure after merge of the drm tree

Hi Dave,

After merging the drm tree, today's linux-next build (x86_64 allmodconfig)
failed like this:

drivers/gpu/drm/i915/intel_ddi.c: In function 'intel_prepare_ddi_buffer':
drivers/gpu/drm/i915/intel_ddi.c:447:15: error: 'struct drm_i915_private' has no member named 'edp_low_vswing'
   if (dev_priv->edp_low_vswing) {
               ^

Caused by commit

  06411f08b3f3 ("drm/i915: move edp low vswing config to vbt data")

interacting with commit

  992e7a41f9fc ("drm/i915: Fix eDP low vswing for Broadwell")

from the drm-intel-fixes tree.

I applied the following merge fixup patch (which is suggested by the "v3:
Change dev_priv->edp_low_vswing to use dev_priv->vbt.edp.low_vswing"
comment in the drm-intel-fixes tree patch, but clearly could not be
done there).
