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

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

From: Peter Meerwald <pmeerw@...erw.net>

commit 33361e5678a541f82f29f85467d589e7bf8da76b upstream.

the millisecond values in tcs3414_times should be checked against
val2, not val, which is always zero.
