Subject: [PATCH 0/6] lib/crypto: More at_least decorations

This series depends on the 'at_least' macro added by
https://lore.kernel.org/r/20251122025510.1625066-4-Jason@zx2c4.com
It can also be retrieved from

    git fetch https://git.kernel.org/pub/scm/linux/kernel/git/ebiggers/linux.git more-at-least-decorations-v1

Add the at_least (i.e. 'static') decoration to the fixed-size array
parameters of more of the crypto library functions.  This causes clang
to generate a warning if a too-small array of known size is passed.

Eric Biggers (6):
  lib/crypto: chacha: Add at_least decoration to fixed-size array params
  lib/crypto: curve25519: Add at_least decoration to fixed-size array
    params
  lib/crypto: md5: Add at_least decoration to fixed-size array params
  lib/crypto: poly1305: Add at_least decoration to fixed-size array
    params
  lib/crypto: sha1: Add at_least decoration to fixed-size array params
  lib/crypto: sha2: Add at_least decoration to fixed-size array params
