Subject: [PATCH 4.2.y-ckt 158/206] mfd: lp8788-irq: Uninitialized variable in irq handler

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

From: Dan Carpenter <dan.carpenter@...cle.com>

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.

Fixes: eea6b7cc53aa ('mfd: Add lp8788 mfd driver')
