Subject: [GIT PULL] Power management fixes for v5.19-rc6

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.19-rc6

with top-most commit fe7c758c07c4729a16f940eb1d77027ad032ab29

 Merge branch 'pm-core'

on top of commit 88084a3df1672e131ddc1b4e39eeacfd39864acf

 Linux 5.19-rc5

to receive power management fixes for 5.19-rc6.

These fix a NULL pointer dereference in a devfreq driver and
a runtime PM framework issue that may cause a supplier device
to be suspended before its consumer.

Specifics:

 - Fix NULL pointer dereference related to printing a diagnostic
   message in the exynos-bus devfreq driver (Christian Marangi).

 - Fix race condition in the runtime PM framework which in some
   cases may cause a supplier device to be suspended when its
   consumer is still active (Rafael Wysocki).

Thanks!
