From: Cao Guanghui <[email protected]> era_ctr() replaces the actual error codes returned by dm_get_device() and dm_set_target_max_io_len() with hardcoded -EINVAL, discarding the real reason for the failure (e.g. -ENODEV, -ENOMEM). This makes it harder for users to diagnose problems and is inconsistent with other dm targets (dm-thin, dm-verity, dm-flakey, dm-ebs) which propagate the original error.
Fix all three sites to return 'r' instead of -EINVAL.
