huh, this should have been "internal errors", which should make a bit more
sense. and yes, the above was pretty much what I was trying to say. I've
reworded this now to:
libinput_udev_create_for_seat() succeeds even if no input device is
available in this seat, or if devices are available but fail to open in
@ref libinput_interface::open_restricted. Devices that do not have the
minimum capabilities to be recognized as pointer, keyboard or touch
device are ignored. Such devices and those that failed to open are
ignored until the next call to libinput_resume().
