[GIT PULL] keys: Changes for 5.8

[David Howells]

Hi Linus,

Could you pull these keyrings fixes please?

 (1) Fix a documentation warning.

 (2) Replace a [0] array with [].

 (3) Make the big_key key type use ChaCha20Poly1305 and use the crypto
     algorithm directly rather than going through the crypto layer.

 (4) Implement the update op for the big_key type.

Thanks,
David
