Date: Thu Jun 09 2016 - 17:34:50 EST


4.2.8-ckt12 -stable review patch. If anyone has any objections, please let me know.

commit 22aab38e7b59fd79ce1045006be69a9abab58e5a upstream.

Instead to being true/false, the "handled" is true/uninitialized.
Presumably this doesn't cause that many problems in real life because
normally we handle the IRQ.
