Ok I have produced some 14.10 (utopic) kernels with this proposed fix
applied.  If someone could urgently test these and report back we should
be able to get this into the release.  Kernels are at the URL below:

Please report any testing back here.

Bug description:
  the left touchpad button of my lenovo g50 laptop stopped working in the kernel upgrade 3.16.0-22 #29
  The rest of the touchpad and the right button are still working.
  the previous kernel version #27 worked fine
