[PATCH v9 18/22] cryptodisk: Fallback to passphrase

[Gary Lin]

From: Patrick Colp <patrick.colp@oracle.com>

If a protector is specified, but it fails to unlock the disk, fall back
to asking for the passphrase. However, an error was set indicating that
the protector(s) failed. Later code (e.g., LUKS code) fails as
`grub_errno` is now set. Print the existing errors out first, before
proceeding with the passphrase.
