Subject: [GIT PULL] Power management fixes for v5.15-rc2
Hi Linus,
Please pull from the tag
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
pm-5.15-rc2
with top-most commit cdef1196608892b9a46caa5f2b64095a7f0be60c
cpufreq: schedutil: Destroy mutex before kobject_put() frees the memory
on top of commit 6880fa6c56601bb8ed59df6c30fd390cc5f6dd8f
Linux 5.15-rc1
to receive power management fixes for 5.15-rc2.
These fix two cpufreq issues, one in the intel_pstate driver and one
in the core.
Specifics:
- Prevent intel_pstate from avoiding to use HWP, even if instructed
to do so via the kernel command line, when HWP has been enabled
already by the platform firmware (Doug Smythies).
- Prevent use-after-free from occurring in the schedutil cpufreq
governor on exit by fixing a core helper function that attempts
to access memory associated with a kobject after calling
kobject_put() on it (James Morse).
Thanks!
