Getting:
Applying: tpm: Reserve the TPM final events table error: sha1 information is lacking or useless (drivers/firmware/efi/efi.c). error: could not build fake ancestor

My guess is that your patches are based a later 5.0-rcX. Unfortunately I cannot update my master at this point because my 5.1 PR was taken to security tree and rebasing would change the commit IDs of 5.1 content because security/next-general does not yet contain those patches.
