Subject: [PATCH] Revert "HID: magicmouse: Set multi-touch keybits for Magic Mouse"

Setting these bits causes libinput to fail to initialize the device;
setting BTN_TOUCH and BTN_TOOL_FINGER causes it to treat the mouse as a
touchpad, and it then refuses to continue when it discovers ABS_X is not
set.

This breaks all known Wayland compositors, as well as Xorg when the
libinput driver is being used.

This reverts commit f4b65b9563216b3e01a5cc844c3ba68901d9b195.

Jiri, can you please get this into 4.12 final?

Right. The revert is required as this is a regression.

However, I wonder if we should not find a better solution than having
this hybrid device that is part touchpad, part mouse.

Cheers,
Benjamin

What happens if you set ID_INPUT_MOUSE and unset ID_INPUT_TOUCHPAD with a
udev rule/hwdb entry? I think it should work then although we'll ignore the
touch bits - that mouse would require some special handling in libinput to
expose all its features.
