From cb0ffbcd86756a47696b6e24e19552d2bcc4238a Mon Sep 17 00:00:00 2001

Subject: [PATCH 14/16] SecurityPkg: add TIS sanity check (tpm2)
The code blindly assumes a TIS interface is present in case both CRB and
FIFO checks fail. Check the InterfaceType for TIS instead and only
return Tpm2PtpInterfaceTis in case it matches, Tpm2PtpInterfaceMax
otherwise.
