> Not displaying the flip on the next vblank is bad, but not the end of

> a few more frames to complete, and warn instead of failing if it takes
> more than one vblank interval to flip.

> v2: Bump the warning to >1 missed flip, to spare us the noise.

Thanks! Last failure seen was 8 days ago, so we'll monitor that.
However, I am lazy and I don't want to write another bug report for the other
failures, so let's repurpose this bug for the other issue:
<a href="https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_250/fi-bsw-n3050/igt@kms_cursor_legacy@long-nonblocking-modeset-vs-cursor-atomic.html">https://intel-gfx-ci.01.org/tree/drm-tip/drmtip_250/fi-bsw-n3050/igt@kms_cursor_legacy@long-nonblocking-modeset-vs-cursor-atomic.html</a>
