Merge branch 'drm-intel-next-fixes' into drm-intel-next
So I've sent the first pull request to Dave and I expect his request
for a merge tree any second now ;-)
More seriously I have some pending patches for 3.19 that depend upon
both trees, hence backmerge. Conflicts are all trivial.
Conflicts:
drivers/gpu/drm/i915/i915_irq.c
drivers/gpu/drm/i915/intel_display.c
v2: Of course I've forgotten the fixup script for the silent conflict.
