PCI Hotplug: fakephp: fix deadlock... again
Commit fe99740cac117f208707488c03f3789cf4904957 (construct one
fakephp slot per PCI slot) introduced a regression, causing a
deadlock when removing a PCI device.
We also never actually removed the device from the PCI core.
So we:
- remove the device from the PCI core
- do not directly call remove_slot() to prevent deadlock
Yu Zhao reported and diagnosed this defect.
