e20bbe7002
The return code of assign_parent remained unused. So this patch removes it. The bind_thread function fails only due to platform-specific limitations such as the exhaustion of ID name spaces, which cannot be sensibly handled by the PD-session client. If occurred, such conditions used to be reflected by integer return codes that were used for diagnostic messages only. The patch removes the return codes and leaves the diagnostic output to core. Fixes #1842
