Add new API call: evdev_register_mtx which takes lock argument that should be used instead of internal one for evdev locking. Useful for cases if evdev_push_event() is always called with driver's lock taken and reduces amount of lock aquisitions. This allows to avoid LOR between ev_open/ev_close invocations and evdev_push_event() Such LOR can happen when ev_open/ev_close methods acquire driver lock and evdev_push_event() is called with this lock taken. Submitted by: Vladimir Kondratiev <wulf@cicgroup.ru> r306857: Implement EVDEV_FLAG_MT_AUTOREL flag (autorelease touchpoints) Automaticaly release (send ABS_MT_TRACKING_ID = -1) MT-slots that has not been listed in current MT protocol type B report. Slot is counted as listed if corresponding ABS_MT_SLOT event has been sent regardless of other MT events. Events are sent on SYN_REPORT event. Submitted by: Vladimir Kondratiev <wulf@cicgroup.ru>

r305706: Add evdev protocol implementation evdev is a generic input event interface compatible with Linux evdev API at ioctl level. It allows using unmodified (apart from header name) input evdev drivers in Xorg, Wayland, Qt. This commit has only generic kernel API. evdev support for individual hardware drivers like ukbd, ums, atkbd, etc. will be committed later. Project was started by Jakub Klama as part of GSoC 2014. Jakub's evdev implementation was later used as a base, updated and finished by Vladimir Kondratiev.

This is valid value and should not cause crash. In this case evdev_free does nothing Submitted by: Vladimir Kondratiev <wulf@cicgroup.ru>
