Subject: fastmodel: Return nullptr from getCheckerCpuPtr on fast model CPUs.
X-Git-Tag: v20.0.0.0~469

fastmodel: Return nullptr from getCheckerCpuPtr on fast model CPUs.

Fast model CPUs won't (at least as of now) have a checker CPU attached
to them. We can safely return nullptr to signal that to calling code.
