TPM DEVICE DRIVER updates for tpmdd-next-v5.18-rc4

Hi,

Mickaël's patches to add signed hash to the blacklist keyring that were left out from the original v5.18 PR. They should be safe to include to rc4 as they've been in circulation for ages, and have been tested throughly.

BR, Jarkko

Barring a bit in patch 3 where I think strncmp() would be better employed for checking prefixes (and can be fixed up later):

Thanks David.
