Pull power management fixes from Rafael Wysocki:
"These address system suspend failures under memory pressure in some
configurations, fix up RAPL handling on platforms where PL1 cannot be
disabled, and fix a documentation typo:
- Prevent the Intel RAPL power capping driver from allowing PL1 to be
exceeded by mistake on systems when PL1 cannot be disabled (Zhang
Rui)
- Fix a typo in the ABI documentation (Sumanth Gavini)
- Allow swap to be used a bit longer during system suspend and
hibernation to avoid suspend failures under memory pressure (Mario
Limonciello)"
* tag 'pm-6.16-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
PM: sleep: docs: Replace "diasble" with "disable"
powercap: intel_rapl: Do not change CLAMPING bit if ENABLE bit cannot be changed
PM: Restrict swap use to later in the suspend sequence
