Merge tag 'devfreq-next-for-6.2' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux
Pull devfreq updates for 6.2 from Chanwoo Choi:
"- Add a private governor_data for governor.
The private governor_data is allocated and handled by governor
regardless of passing the data from devfreq driver via
devfreq_add_device. The added private governor data keeps the
governor own data when switching from userspace
governor and other governors.
- Replace code by using defined functions of
device_match_of_node() and devm_platform_get_and_ioremap_resource()."
