+Subject: drm/i915: Correctly set SFC capability for video engines
+
+From: Venkata Sandeep Dhanalakota <venkata.s.dhanalakota@intel.com>
+
+commit 5ce6861d36ed5207aff9e5eead4c7cc38a986586 upstream.
+
+SFC capability of video engines is not set correctly because i915
+is testing for incorrect bits.
+
+Fixes: c5d3e39caa45 ("drm/i915: Engine discovery query")
