I think it is actually a regression in 4d23cc323cdb. Should carry a
fixes tag. I did not quite undersand what commit message was saying.
What it should would just

tpm: Fix the type of the return value in calc_tpm2_event_size()

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

Should be also Cc'd to linux-security-module and have cc to stable.
