calc_tpm2_event_size() has an invalid signature because
it returns a 'size_t' where as its signature says that
it returns 'int'.

Fixes: 4d23cc323cdb ("tpm: add securityfs support for TPM 2.0 firmware event log")

Two remarks:

- git config user.name "Yue Haibing"
- "Cc: stable@vger.kernel.org" before the fixes tag.

'Theoretical' bug fixes are not suitable for stable

AFAIK there is no hard rule here. For this one line change I think it
makes sense to backport it even if it is only for avoiding conflicts
with future backports.
