Input: synaptics - report multi-taps only if supported by the device
According to Section 2.4.4 of the Synaptics TouchPad Interfacing Guide, bit 2 specifies if multi-finger detection is provided by the touchpad. Thus, only set BTN_TOOL_DOUBLETAP and BTN_TOOL_TRIPLETAP if the device actually supports it. Signed-off-by: Peter Hutterer <peter.hutterer@redhat.com> Signed-off-by: Dmitry Torokhov <dtor@mail.ru>
