The integrated button on the new unibody Macbooks presents a need to
|
|
report explicit four-finger actions. Evidently, the finger pressing
|
|
the button is also touching the trackpad, so in order to fully support
|
|
three-finger actions, the driver must be able to report four-finger
|
|
actions. This patch adds a new button, BTN_TOOL_QUADTAP, which
|
|
achieves this.
