the intel-pstate driver does not support the ondemand governor and does not have a valid value in /sys/devices/system/cpu/cpu[x]/cpufreq/cpuinfo_transition_latency. The intel-pstate driver sets cpuinfo_transition_latency to CPUFREQ_ETERNAL (-1), the value written into cpuinfo_transition_latency is defind as an unsigned int so checking the read value against max unsigned int will determine if the value is valid.
