Revert "Input: clear BTN_RIGHT/MIDDLE on buttonpads"
This reverts commit 37ef4c19b4c659926ce65a7ac709ceaefb211c40.
The touchpad present in the Dell Precision 7550 and 7750 laptops
reports a HID_DG_BUTTONTYPE of type MT_BUTTONTYPE_CLICKPAD. However,
the device is not a clickpad, it is a touchpad with physical buttons.
In order to fix this issue, a quirk for the device was introduced in
libinput [1] [2] to disable the INPUT_PROP_BUTTONPAD property:
[Precision 7x50 Touchpad]
MatchBus=i2c
MatchUdevType=touchpad
MatchDMIModalias=dmi:*svnDellInc.:pnPrecision7?50*
AttrInputPropDisable=INPUT_PROP_BUTTONPAD
However, because of the change introduced in 37ef4c19b4 ("Input: clear
BTN_RIGHT/MIDDLE on buttonpads") the BTN_RIGHT key bit is not mapped
anymore breaking the device right click button and making impossible to
workaround it in user space.
In order to avoid breakage on other present or future devices, revert
the patch causing the issue.
