PM / devfreq: Use PM QoS for sysfs min/max_freq (2019-12-09 12:19:16 +0900)
----------------------------------------------------------------
Update devfreq for 5.5-rc2
Detailed description for this pull request: 1. 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 the issue such as fixing the return value and modify code for more correct exception handling if error happen.
