From: Colin Ian King <colin.king@xxxxxxxxxxxxx>
Currently an error return is being assigned to an unsigned
size_t varianle and then checked if the result is less than
zero which will always be false. Fix this by making ret
ssize_t rather than a size_t.
Fixes: 0322913cab79 ("scsi: target: Add device product id and revision configfs attributes")
