- Touch the touchpad with one finger and move it: this moves the cursor

- Release a finger: you should now be able to move the cursor again.  This
is the part that does not work in one of the patch

   Sorry, I didn't realise that one of my patch submitted a few months ago
(namely, http://www.spinics.net/lists/linux-input/msg19443.html) isn't
in the master tree, which is different from my local working copy.

   With the correct flag(FSP_BIT_SWC1_EN_GID) being set, the hardware
clears MFMC bit during 2 -> 1 finger transition.  The attached patch is
an aggregated version against Dmitry's master branch, which supposes to fix
the testing case listed above.

Thanks,

I am testing against the stable 3.4.y branch.
With that patch, scrolling is very slow, and it emits middle click sometimes 
while I want to scroll fast. 

Looking at the debug output, i see a lot of NOTIFY packets, for the same  
number of packets/seconds (77). So then there is 5 times less multi touch 
events. Maybe that's why.
