Merge tag 'pm-6.19-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management fixes from Rafael Wysocki:
 "These fix an error path memory leak in the energy model management
  code, fix a kerneldoc comment in it, and fix and revamp the energy
  model YNL specification added recently along with the new energy model
  management netlink interface (that received feedback after being
  added):

   - Fix a memory leak in em_create_pd() error path (Malaya Kumar Rout)

   - Fix stale description of the cost field in struct em_perf_state to
     reflect the current code (Yaxiong Tian)

   - Fix and revamp the energy model YNL specification added recently
     along with the energy model netlink interface (Changwoo Min)"

* tag 'pm-6.19-rc6' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm:
  PM: EM: Add dump to get-perf-domains in the EM YNL spec
  PM: EM: Change cpus' type from string to u64 array in the EM YNL spec
  PM: EM: Rename em.yaml to dev-energymodel.yaml
  PM: EM: Fix yamllint warnings in the EM YNL spec
  PM: EM: Fix memory leak in em_create_pd() error path
  PM: EM: Fix incorrect description of the cost field in struct em_perf_state
