From f5e5ab910b8b1d69f962ca033d1295c3e1e1e131 Mon Sep 17 00:00:00 2001
From: Daiki Ueno <ueno@gnu.org>
Date: Wed, 23 Feb 2022 19:48:52 +0100
Subject: [PATCH] tpm2: dynamically load tss2 libraries as needed
libtss2-esys links to OpenSSL or mbed TLS for cryptography, which may
cause packaging issues. This instead dlopen's tss2 libraries as
needed so non-TPM applications continue working without loading
multiple crypto libraries.
