Subject: [GIT PULL] Power management fixes for v5.4-rc4

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-5.4-rc4

with top-most commit b23eb5c74e6eb6a0b3fb9cf3eb64481a17ce1cd1

 Merge branches 'pm-cpufreq' and 'pm-sleep'

on top of commit 4f5cafb5cb8471e54afdc9054d973535614f7675

 Linux 5.4-rc3

to receive power management fixes for 5.4-rc4.

These include a fix for a recent regression in the ACPI CPU
performance scaling code, a PCI device power management fix,
a system shutdown fix related to cpufreq, a removal of an ACPI
suspend-to-idle blacklist entry and a build warning fix.

Specifics:

 - Fix possible NULL pointer dereference in the ACPI processor
   scaling initialization code introduced by a recent cpufreq
   update (Rafael Wysocki).

 - Fix possible deadlock due to suspending cpufreq too late during
   system shutdown (Rafael Wysocki).

 - Make the PCI device system resume code path be more consistent
   with its PM-runtime counterpart to fix an issue with missing
   delay on transitions from D3cold to D0 during system resume from
   suspend-to-idle on some systems (Rafael Wysocki).

 - Drop Dell XPS13 9360 from the LPS0 Idle _DSM blacklist to make it
   use suspend-to-idle by default (Mario Limonciello).

 - Fix build warning in the core system suspend support code (Ben
   Dooks).

Thanks!
