[PATCH 3/4] media: uvcvideo: Return -EACCES for Wrong state error
From: Ricardo Ribalda
Date: Thu Sep 09 2021 - 11:01:29 EST
For error 2 (Wrong state) return -EACCES instead of -EILSEQ.
EACCES is a much more appropriate error code. EILSEQ will return
"Invalid or incomplete multibyte or wide character." in strerror(),
which is a *very* confusing message.
