Pull devfreq updates for 5.5-rc1 from Chanwoo Choi:

"Update devfreq core:

 - Add PM QoS support for devfreq device with following QoS type.
   External user of devfreq device can request the minimum and
   maximum frequency according to their multiple requirements.
   : DEV_PM_QOS_MIN_FREQUENCY is used for requesting the minimum
     device frequency.
   : DEV_PM_QOS_MAX_FREQUENCY is used for requesting the maximum
     device frequency.

 - Use PM QoS interface when entering the min/max_freq via sysfs
   interface.

 - Add get_freq_range() helper function in order to get the final
   min/max frequency among the multiple requirements of min/max
   frequency.

 - Fix a function return value and modify code for more correct
   exception handling if errors happen."
