Input: trackpoint - add new trackpoint firmware ID
commit ec667683c532c93fb41e100e5d61a518971060e2 upstream.
Synaptics add new TP firmware ID: 0x2 and 0x3, for now both lower 2 bits
are indicated as TP. Change the constant to bitwise values.
This makes trackpoint to be recognized on Lenovo Carbon X1 Gen5 instead
of it being identified as "PS/2 Generic Mouse".

Input: trackpoint - assume 3 buttons when buttons detection fails
Trackpoint buttons detection fails on ThinkPad 570 and 470 series,
this makes the middle button of the trackpoint to not being recogized.
As I don't believe there is any trackpoint with less than 3 buttons this
patch just assumes three buttons when the extended button information
read fails.

Please try 4.13.0 kernel, not stable branch, this will make middle
button work.

Title:
Middle button of trackpoint doesn't work
Status in HWE Next:
In Progress
Status in linux package in Ubuntu:
In Progress
Bug description:
Middle button doesn't work on several Thinkpad laptops like E570,
E475, E470, E575 and X1Carbon.
When middle button fails to work, logs show:
psmouse serio2: trackpoint: failed to get extended button data
It fails to read out ext button info via PS2 command.
Almost all the Thinkpad have 3 buttons, so set it to 3 button when it fails
to read button info.
And on Lenovo X1, there is a new version of trackpoint, add this ID
for this new device.
