A comment removed by this commit gives two reasons for listening to slave devices, both of which no longer apply: - "Only slaves emit raw motion events": perhaps this was true when the comment was written, but now master devices provide raw motion events along with the other raw events. - "Selecting slave keyboards avoids dealing with key focus": we get raw key events regardless of the focus. Listening to both master and slave devices results in duplicate raw events. For button and key events, that's a tiny waste of time setting the update flag a second time, but for raw mouse events the raw motion will be processed twice. That makes this commit a user-facing change.
