Public bug reported:
[Impact]
New generations of Realtek PCIe card reader cannot detect card insertion
when the device is in PCI D3.
[Fix]
Rework the runtime PM flow and add chip specific support.
[Test]
With the series applied, the device can detect card insertion when it's
in PCI D3.
[Where problems could occur]
System wide power management with less usage like hibernation, kexec
reboot, etc. are not tested extensively. So these cases may be affected.
