Bug Description
[Impact]
On one of the latest Lenovo laptops, the trackpoint doesn't work, we
consulted apls guys, they said this trackpoint is different from others,
it is a trackpoint-only device, so the current alps.c doesn't support it
well, while the trackpoint.c can drive it well.
[Fix]
Check if it is trakcpoint-only device, if it yes, let trackpoint.c
handle it.
[Test Case]
apply this patch and boot with the kernel, the trackpoint can work
well.
[Regression Risk]
Low. the way of detect trackpoint-only alps device is provided by
alps. so it is pretty safe.
