Merge tag 'devfreq-next-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux
Pull devfreq changes for v6.19 from Chanwoo Choi:
"- Move governor.h under include/linux/ and rename to devfreq-governor.h
in order to allow devfreq governor definitions in out of drivers/devfreq/.
- Fix potential use-after-free issue of OPP handling on hisi_uncore_freq.c
- Use min() to improve the readability on tegra30-devfreq.c
- Fix typo in DFSO_DOWNDIFFERENTIAL macro name on governor_simpleondemand.c"
* tag 'devfreq-next-for-6.19' of git://git.kernel.org/pub/scm/linux/kernel/git/chanwoo/linux:
