commit 32312418625764cdf740890ac9c78ca26a6a9d24 upstream
calc_tpm2_event_size() has an invalid signature because it returns a 'size_t' where as its signature says that it returns 'int'.

But it seems like it breaks the build:

Probably because c8faabfc6f480 is missing. I've reverted this patch from stable for now.
