Subject: tpm2-setup: call DLOPEN_TPM2 to add dependency and fail immediately if not present
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a7aa25bb25601a4242a077796b506faff958fd92;p=thirdparty%2Fsystemd.git

tpm2-setup: call DLOPEN_TPM2 to add dependency and fail immediately if not present

tpm2-setup requires both libcrypto and the tpm2-tss libraries, but so
far it only directly dlopen'ed libcrypto, with a clear error on startup
if missing, and a dependency added via dlopen notes.
Do the same for the tpm2-tss dlopens, to get a clear error and the
required dependencies.
