This still shouldn't be a switch clause because you're hiding the return
-1; in the default label. I think it would be better to write:
if (current_cpu_data.x86 == 15 || current_cpu_data.x86 == 16)
PFM_INFO("found family=%d", current_cpu_data.x86);
else {
PFM_INFO("unsupported family=%d", current_cpu_data.x86);
return -1;
}
