For some reason on 32bit this does not build. The OpenSSL d is unsigned int
AFAICT and the swtpm d is uint32_t. gcc does not tell what pointer types it
compares when it gives a mismatch error. Use an inline function so the pointers
are passed as arguments and any mismatch is reported including exact type.

%description
An implementation of the TCG TPM 2.0 specification. It is based on the TPM specification Parts 3 and 4 source code donated by Microsoft, with additional files to complete the implementation.
This TPM emulator listens on TCP ports (default 2321 and 2322) and saves state to file NVChip in current directory.
It is probably not of much use other than testing the IBM TSS implementation because of this specific interface.
