Input: synaptics - add quirk for Thinkpad E440
Its ClickPad shares PNP ID "LEN2006" with the one in model E540 which is already handled by the driver (both are Haswell iterations of the Edge line, launched in 2014) but the dimensions it reports are different: $ sudo ./touchpad-edge-detector /dev/input/event3 Touchpad SynPS/2 Synaptics TouchPad on /dev/input/event3 Move one finger around the touchpad to detect the actual edges Kernel says: x [1472..5044], y [1408..3398] Touchpad sends: x [1024..5045], y [2457..4832] /^C Fortunately we can use the board ID, which is also different, to distinguish among them. $ dmesg | grep -i synaptics psmouse serio1: synaptics: Touchpad model: 1, fw: 8.1, id: 0x1e2b1, caps: 0xd001a3/0x940300/0x127c00, board id: 2691, fw id: 1494646 psmouse serio1: synaptics: serio: Synaptics pass-through port at isa0060/serio1/input0 input: SynPS/2 Synaptics TouchPad as /devices/platform/i8042/serio1/input/input4 Board ID in E540 is 2722: psmouse serio1: synaptics: Touchpad model: 1, fw: 8.1, id: 0x1e2b1, caps: 0xd001a3/0x940300/0x127c00, board id: 2722, fw id: 1484859 (from https://launchpadlibrarian.net/179702965/BootDmesg.txt) Signed-off-by: Ramiro Morales <cramm0@gmail.com> Reviewed-by: Benjamin Tissoires <benjamin.tissoires@redhat.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>
