Subject[PATCH 4.19 87/96] tpm: Fix the type of the return value in calc_tpm2_event_size()
Date
commit b9d0a85d6b2e76630cfd4c475ee3af4109bfd87a upstream

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

Cc: <stable@vger.kernel.org>
Fixes: 4d23cc323cdb ("tpm: add securityfs support for TPM 2.0 firmware event log")
