[ Upstream commit 9d5171eab462a63e2fbebfccf6026e92be018f20 ]
The original patch 8c657a0590de ("KEYS: trusted: Reserve TPM for seal
and unseal operations") was correct on the mailing list:
https://lore.kernel.org/linux-integrity/20210128235621.127925-4-jarkko@kernel.org/
But somehow got rebased so that the tpm_try_get_ops() in
tpm2_seal_trusted() got lost. This causes an imbalanced put of the
TPM ops and causes oopses on TIS based hardware.
This fix puts back the lost tpm_try_get_ops()
Fixes: 8c657a0590de ("KEYS: trusted: Reserve TPM for seal and unseal operations")
