[PATCH 0/1] [Jaunty] LP#317270 -- fix Synaptics touchpad resume

Some systems with newer Synaptics touchpads have been exhibiting total
touchpad failure following resume on Linux, but functioning correctly on
other OSs.  Serial analysis has shown that this is caused by a lack of
a device reset on resume in Linux.  The following patch adds this reset
to the Synaptics driver.

It is expected that this should be safe for all Synaptics devices old and
new as the other OSs have always used this method of reset.  Therefore we
enable this new functionality by default.  We also provide a new module
option to disable it, and hint as to its name in the dmesg, should anyone
see issues.  By enabling this now for the beta cycle we should have time
to shake out any regressions this might cause.
