Hi:

I have tried setting module parameter disable_aspm=1, but it's not useful.

By git blame command, I know that the assignment of .driver.pm =

was in commit 44bc17f7f5b3b("rtw88: support wowlan feature for
8822c"),

and another commit 7dc7c41607d19("avoid unused function warnings")

pointed out rtw_pci_resume() and rtw_pci_suspend() are not used at
all.

So I think it's safe to remove them.

I think ".driver.pm = &rtw_pm_ops" is a switch to enable wowlan feature.
That means that wowlan doesn't work without this declaration.

Currently, I find that the rtl8822ce wifi chip and the pci bridge of
it are not linked by pci

after wake up by `lspci` command.

when I set `pcie_aspm.policy=performance ` in the GRUB. The machine
sleep and

wake up normal.So I think when this ops is assignmented,the sleep and
wake up procedure

may cause pci device not linked.
Please try setting module parameter disable_aspm=1 with pci.ko.

Could I know what the CPU and pci bridge chipset are used by HONOR laptop?
