Thermal: cpufreq cooling: endian bug in cpufreq_get_max_state()
This code doesn't work on big endian systems because we're storing low values in the high bits of the unsigned long. It makes it a very high value instead. Signed-off-by: Dan Carpenter <dan.carpenter@oracle.com> Signed-off-by: Zhang Rui <rui.zhang@intel.com>
