Subject: Add LIBEVENT_EVENT_NONE
X-Git-Tag: 0.1.0~90
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=90fa77908bb6254acc819ec1f7b49613edf413d5;p=platform%2Fupstream%2Flibinput.git

Add LIBEVENT_EVENT_NONE

This event type is needed to notify callers that there is currently no
event waiting (in a follow-up patch). Also, it it avoids true/false
inconsistencies on event types (LIBINPUT_EVENT_ADDED_SEAT would otherwise be
the only FALSE event). While that's not technically necessary, it may prevent
the odd bug further down the road.
