Subject: [GIT PULL] Power management fixes for v5.12-rc4

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.12-rc4

with top-most commit 49cb71a77ce760f20487c38f891aa3132bef782e

 Merge branch 'pm-core'

on top of commit 1e28eed17697bcf343c6743f0028cc3b5dd88bf0

 Linux 5.12-rc3

to receive power management fixes for 5.12-rc4.

These revert two problematic commits.

Specifics:

 - Revert ACPI PM commit that attempted to improve reboot handling
   on some systems, but it caused other systems to panic() during
   reboot (Josef Bacik).

 - Revert PM-runtime commit that attempted to improve the handling
   of suppliers during PM-runtime suspend of a consumer device, but
   it introduced a race condition potentially leading to unexpected
   behavior (Rafael Wysocki).

Thanks!
