r306647:
const-ify struct evdev_methods
Submitted by: Vladimir Kondratiev <wulf@cicgroup.ru>
Suggested by: hselasky
r306855:
Allow using of driver's mutex instead internal one for evdev locking.
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.

has been sent regardless of other MT events.
