Subject: ecore-drm: Create drmEventContext Once during device open
X-Git-Tag: v1.14.0-beta1~55
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=3832cd59b8102b063fe65c7f0fe81626da285455;p=platform%2Fupstream%2Fefl.git

ecore-drm: Create drmEventContext Once during device open

Summary: This changes allows us to reuse the same drmEventContext once
so that when we get drm events, we are not constantly recreating the
drmEventContext.

@fix
