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

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

From: Dmitry Torokhov <redacted>

commit 50c5d36dab930b1f1b1e3348b8608aa8b9ee7610 upstream.

We attempt to remove noise from coordinates reported by devices in
input_handle_abs_event(), unfortunately, unless we were dropping the
event altogether, we were ignoring the adjusted value and were passing
on the original value instead.
