Merge tag 'pm-7.0-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki:
"These fix a potential NULL pointer dereference in the energy model
netlink interface and a potential double free in an error path in
the common cpufreq governor management code:
- Fix a NULL pointer dereference in the energy model netlink
interface that may occur if a given perf domain ID is not
recognized (Changwoo Min)
- Avoid double free in the cpufreq_dbs_governor_init() error
path when kobject_init_and_add() fails (Guangshuo Li)"

cpufreq: governor: fix double free in cpufreq_dbs_governor_init() error path
