  KEYS: trusted: Do not use WARN when encode fails (2024-05-21 02:35:10 +0300)

----------------------------------------------------------------
Hi,

These are couple of bugs I found from trusted keys while working on a new
asymmetric key type for TPM2 [1]. Both originate form v5.13. Memory leak is
more crucial but I don't think it is either good idea if kernel throws WARN
when ASN.1 parser fails, even if it is related to programming error, as it
is not that mature code yet.

There's at least two WARN's in that code but I picked just the one more
likely to trigger. Planning to fix the other one too over time.

BR, Jarkko
