Using struct pci_platform_pm_ops for ACPI adds unnecessary
indirection to the interactions between the PCI core and ACPI PM,
which is also subject to retpolines.
Moreover, it is not particularly clear from the current code that,
as far as PCI PM is concerned, "platform" really means just ACPI
except for the special casess when Intel MID PCI PM is used or when
ACPI support is disabled (through the kernel config or command line,
or because there are no usable ACPI tables on the system).
To address the above, rework the PCI PM code to invoke ACPI PM
functions directly as needed and drop the acpi_pci_platform_pm
object that is not necessary any more.
Accordingly, update some of the ACPI PM functions in question to do
extra checks in case the ACPI support is disabled (which previously
was taken care of by avoiding to set the pci_platform_ops pointer
in those cases).

v1 -> v2:
* Rebase on top of the new [1/7] and move dropping struct
pci_platform_pm_ops to a separate patch.
I wanted to test this series on 5.15-rc2 but this patch 2/7 doesn't
apply (after 1/7 applied). Should I apply this on another tree?
This is on top of
https://patchwork.kernel.org/project/linux-acpi/patch/2793105.e9J7NaK4W3@kreacher/
which is not yet in any tree.
Sorry for the confusion.
No problem at all. If I can I will try to report back tonight. Else,
will be delayed 2 due to a short break.
With those 3 extra patches followed by 7 from this series it builds. But
on boot I get:
dwc3 dwc3.0.auto: this is not a DesignWare USB3 DRD Core
Then after this it reboots. Nothing in the logs. Nothing else on
console, I guess something goes wrong early.
It appears so.
Can you please try just the 3 extra patches this series is on top of?
The problem is more likely to be located in one of them.
Yes, I hope to be able to that this evening.
