Merge tag 'pm-6.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm
Pull power management fixes from Rafael Wysocki:
"These fix two cpufreq issues, one in the core and one in the
intel_pstate driver:
- Fix CPU device node reference counting in the cpufreq core (Miquel
Sabaté Solà)
- Turn the spinlock used by the intel_pstate driver in hard IRQ
context into a raw one to prevent the driver from crashing when
PREEMPT_RT is enabled (Uwe Kleine-König)"
* tag 'pm-6.12-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
cpufreq: Avoid a bad reference count on CPU node
cpufreq: intel_pstate: Make hwp_notify_lock a raw spinlock
