[PATCH] drm/i915: Propagate invalid setcrtc cloning errors back to userspace

[PATCH] drm/i915: Propagate invalid setcrtc cloning errors back to userspace

[Matt Roper]

When invalid cloning configurations were detected during modeset, we
never copied the error code into the return value variable, leading us
to return 0 (success) to userspace.

Hmm. Unless I'm mistaken the problem appeared in

I guess this is a regression from 

commit 50f5275698df4490046cc5b4ed2018abb642a803

Is this the one we have a bugzilla for already? Jesse?
