3.16.51-rc1 review patch. If anyone has any objections, please let me know.

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

From: Dmitry Torokhov <dmitry.torokhov@xxxxxxxxx>

commit 39467fc1054a91efa697162a94e5b0e1a4b7b580 upstream.

Instead of stopping the touchscreen we were starting it in suspend, and
disabling it in resume.

Fixes: c899afedf168 ("Input: ucb1400_ts - convert to threaded IRQ")
