File U_03-sna-video-Create-one-XvAdapter-for-each-sprite-plane.patch of Package xf86-video-intel.openSUSE_Leap_42.2_Update

From: Chris Wilson <chris@chris-wilson.co.uk>
Date: Mon Jun 20 11:44:23 2016 +0100
Subject: [PATCH 3/5]sna/video: Create one XvAdapter for each sprite plane
Patch-mainline: ebc5e9c3b2241be69bee7b96bd63ef00dacf816c
Git-repo: git://anongit.freedesktop.org/xorg/driver/xf86-video-intel
References: boo#984747
Signed-off-by: Max Staudt <mstaudt@suse.de>

The caveat here is that the sprite plane must be available on all CRTCs
so that the availability of the XvAdapter is not dependent upon output
configuration or Window placement.

Based on a patch by Michael Hadley <michaelx.hadley@intel.com>
