__blkdev_issue_discard() always returns 0, making the error assignment in __submit_discard_cmd() dead code.
Initialize err to 0 and remove the error assignment from the __blkdev_issue_discard() call to err. Move fault injection code into already present if branch where err is set to -EIO. This preserves the fault injection behavior while removing dead error handling. Reviewed-by: Martin K.
