Re: [PATCH] rtw88: 8822ce: fix wifi disconnect after S3/S4 on HONOR laptop

When the laptop HONOR MagicBook 14 sleep to S3/S4, the laptop can't
resume.
The dmesg of kernel report:
"[   99.990168] pcieport 0000:00:01.2: can't change power state
from D3hot to D0 (config space inaccessible)
[   99.993334] rtw_pci 0000:01:00.0: can't change power state

[  104.435010] rtw_pci 0000:01:00.0: failed to power on mac"
When try to pointer the driver.pm to NULL, the problem is fixed.
This driver hasn't implemented pm ops yet.It makes the sleep and
wake procedure expected when pm's ops not NULL.

But why rtw_pci_suspend() and rtw_pci_resume() are empty? Should we just
remove them if they cause issues for the users? And if they are really
needed there should be a comment in the functions explaining the
situation.

Fixed: commit e3037485c68e ("rtw88: new Realtek 802.11ac driver")

This should be:

Fixes: e3037485c68e ("rtw88: new Realtek 802.11ac driver")
