Currently, we rely on the existence of struct pci_driver::err_handler to decide if the corresponding PCI device should be unplugged during EEH recovery (partially hotplug case). However that check is not sufficient. Some device drivers implement only some of the EEH error handlers to collect diag-data. That means the driver still expects a hotplug to recover from the EEH error. This makes the hotplug criterion more relaxed: if the device driver doesn't provide all necessary EEH error handlers, it will experience hotplug during EEH recovery.
