Subject: Getting weird TPM error after rebasing my tree to
 security/next-general

I get this on a Geminilake NUC after rebasing my maintainer trees:

tpm tpm0: A TPM error (-1) occurred attempting the self test

I checked the latest commit ID from drivers/char/tpm to make sure
that I did not put anything broken to my last PR [1]. It works
without issues.

In addition [2] gives me an empty diff.

Something outside of the TPM driver must have happened that breaks
the driver. Any ideas?

[1] commit 9488585b21bef0df1217e510c7134905d1d376a7
[2] git diff 9488585b21bef0df1217e510c7134905d1d376a7 master drivers/char/tpm/
