The stick device does not work after resume, add U1_SP_ABS_MODE flag can
make the device work after resume.

Do you happen to have any more details on why it doesn't work without
U1_SP_ABS_MODE? Or was this a pure guesswork?

It' pure guesswork, based on how the existing code uses U1_TP_ABS_MODE flag
on both initialization and resume.

I also tested the the patch on an ALPS touchpad without stick device,
did not notice
any side effect on suspend/resume, so I made the U1_SP_ABS_MODE flag mandatory.

I'll fold this information into the patch changelog before comitting; if
you disagree, please let me know.

That will be great.
Appreciate!
