Pull tpm fix from James Bottomley:
"This is an urgent regression fix for a tpm patch set that went in this
merge window. It looks like a rebase before the original pull request
lost a tpm_try_get_ops() so we have a lock imbalance in our code which
is causing oopses. The original patch was correct on the mailing list.
I'm sending this in agreement with Mimi (as joint maintainers of
trusted keys) because Jarkko is off communing with the Reindeer or
whatever it is Finns do when on holiday"
