It certainly can be fixed. But its unlikely (from the time until release) going
into the initial release. The normal path would be to have this patch upstream
(ideally with the proper tag in the signed-off-by area to be picked up by
upstream stable). This ensures that problems are fixed upstream and get proper
upstream review.
If it is marked as stable patch, it will make its way into the kernel. If not,
you should open a launchpad bug with a reference to the fix, so it can be
tracked there.
