To te able to unregister stuff from isrs, the corresponding table was

But there are stack-allocated objects passed to these isrs giving chances
of UAF of these objects if irqs are unregistered while they are handled,
so better do not copy that table.

Looks good to me, applying to drm-misc-next.
It seems not to be on linux-next. somehow this did fall through the cracks?
It did. I applied it to my local dim branch, then went looking for other
omapdrm patches (the dsi one), which took a while and... yes, forgot to
push...
Pushed now to drm-misc-next.
