But the error message is removed in the subsequent patch
"[PATCH 03/17] media: v4l2: async: Add v4l2_async_notifier_add_subdev".
I could bring it back as a dev_dbg() in v4l2_async_notifier_asd_valid(), but
this shouldn't be a dev_err() anymore since it is up to the media platform
to decide whether an already existing subdev descriptor is an error.
