+Subject: [PATCH] media/gpu/vaapi: Relax the version check for VA-API
+
+Since the newer versions of VA-API are ABI compatible, relax the
+version checks for VA-API, by using VA_CHECK_VERSION().
+This will help in updating the libva to the latest releases,
+while still supporting the old versions, till the new version of
+libva is merged and picked by the builds. Thus ensuring that
+hardware accleration is not broken while updating the libva.
+
+Bug: 905814
+TEST=libva-2.3.0 and libva-2.1.0 are able to do hardware acceleration.
