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

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

From: Beomho Seo <beomho.seo@xxxxxxxxxxx>

commit 41c897f8789d0d1039ed873ddcd0caabd5756e0f upstream.

In read integration time function, assign 0 to val.
Because, prevent return inaccurate value when call read integration time.
