Synaptics, CAP_FORCEPAD, bad behavior

Hi!
Just installed the just released 3.17 kernel and found a bad behavior of
the new Synaptics driver on my Thinkpad Yoga which has the new Synaptics
clickpad enabled touchpad:

psmouse serio1: synaptics: Touchpad model: 1, fw: 8.1, id: 0x1e2b1,
caps: 0xd002a3/0x940300/0x12f800, board id: 2911, fw id: 2560

The issue is that now a button release is only issued after the finger
has completely left the touchpad and not when releasing the physical
button. Is this physical button now called FORCEPAD? Anyway, this is
pretty annoying. Double clicking become a real pain.
I did comment out the new

	if (SYN_CAP_FORCEPAD(priv->ext_cap_0c)) {
	...

and everything is back to normal again, i.e. when I do release the pad
physical button but keep the finger on the pad, the button release event
is issued properly.

Cheers
  nicole
