Subject: [GIT PULL] Power management fixes for final v5.0

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.0

with top-most commit 5b317cbf2bcb85a1e96ce87717cb991ecab1dd4d

 Merge branch 'pm-cpufreq-fixes'

on top of commit a3b22b9f11d9fbc48b0291ea92259a5a810e9438

 Linux 5.0-rc7

to receive power management fixes for final 5.0.

These fix a regression in the PM-runtime framework introduced
by the recent switch-over of it to using hrtimers and a
use-after-free introduced by one of the recent changes in the
scmi-cpufreq driver.

Specifics:

 - Use hrtimer_try_to_cancel() instead of hrtimer_cancel() in the
   PM-runtime framework to avoid a possible timer-related deadlock
   introduced recently (Vincent Guittot).

 - Reorder the scmi-cpufreq driver code to avoid accessing memory
   that has just been freed (Yangtao Li).

Thanks!
