   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.

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.

   I see. It appears to me that we'd better to revert back to the last_mt_fgr
workaround to avoid such delay.
