   4 Subject: [PATCH 199/232] drm/vc4: Drop error message on seqno wait timeouts.
   5
   6 These ioctls end up getting exposed to userspace, and having normal
   7 user requests print DRM errors is obviously wrong.  The message was
   8 originally to give us some idea of what happened when a hang occurred,
   9 but we have a DRM_INFO from reset for that.
