3rdparty: Fix forwards-compatibility bug in bundled xinput xcb module
libxcb thinks that it knows about all device class types sent by the X server XInput extension. With the addition of touchpad gestures in XInput 2.4 and X server 21.1 this is no longer the case and libxcb fails horribly by thinking that the protocol was malformed. The X server currently has a workaround, but it would not address the following situation: - there are multiple modules within the same X client (e.g. part of the application uses Qt, another part talks to X server via another library) - both of the modules talk to XI - at least one module requests for XI 2.4 protocol support. The request for XI 2.4 disables the workaround on the X server and Qt side would crash horribly. This bug is being fixed upstream in these MRs: Change-Id: Idf345271340031152b512ef59f619313be5ec226 Reviewed-by: Allan Sandfeld Jensen <> Reviewed-by: Shawn Rutledge <>
