The comment claimed "Keep the detail in the log" while the line it introduces
carries none, so the next reader would have read the omission as an oversight
and added the errno back.
Detail-free is the deliberate choice: a media-fetch failure names the camera's
upstream host, and these lines get pasted into issues. Say that, and say why
the catch at the bottom of this file may still log its error text.
