Subject: [PATCH 3.16.y-ckt 087/144] mfd: kempld-core: Fix callback return value check

3.16.7-ckt10 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Ameya Palande <2ameya@...il.com>

commit c8648508ebfc597058d2cd00b6c539110264a167 upstream.

On success, callback function returns 0. So invert the if condition
check so that we can break out of loop.
