The stable kernel rules are very clear about this:

 - It must be obviously correct and tested.

Please ensure the backport gets tested on a machine that was
affected by the problem.  That doesn't mean we need 100%
confidence that the fix worked, but if I understand you
correctly it is possible that nobody tested the backport on
real hardware at all.

An ack from someone on the i915 team would be welcome as well.

Thanks and hope that helps,
Jonathan
