Well, we could not do anything, sure, that's an option too. It would
only be the annoying error message. Which is
pr_err("no valid rapl domains found in package %d\n", rp->id);
I guess we can tone that down as apparently it is not an error to
not have valid rapl domains anymore. Maybe kill it altogether:
rapl_detect_topology() will propagate the error and the driver won't
load...
