Re: [PATCH 5/5] Cryptomount support for hyphens in UUID

[John Lane]

This revised patch uses a compare function. It doesn't modify the input
supplied by the user.

There are 3 places where UUIDs are compared:
1. when a crypto disk is referenced as a (cryptouuid/...) #cryotodisk.c
grub_cryptodisk_open
2. when the -u argument is given to cryptomount it checks by the uuid
that the device isn't already mounted #cryptodisk.c
grub_cryptodisk_get_by_uuid
3. when locating a device by uuid it compares the given uuid with the
LUKS header #luks.c configure_ciphers
