[PATCH 2/2] Input: synaptics - initialize pointer emulation usage

[Henrik Rydberg]

To properly setup event parameters for emulated events, pass
the appropriate flag to the slot initialization function. Also,
all MT-related events should be setup before initialization.

Incidentally, this solves the issue of doubly filtered pointer
events.

Hi Daniel,

This patch has only been compile tested, but chances are that it will
work for you, together with the previous patch.

Cheers,
Henrik
