+Subject: [PATCH 198/304] drm/vc4: Drop error message on seqno wait timeouts.
+
+These ioctls end up getting exposed to userspace, and having normal
+user requests print DRM errors is obviously wrong.  The message was
+originally to give us some idea of what happened when a hang occurred,
+but we have a DRM_INFO from reset for that.
