In eeh_add_device_late(), pdn is NULL, so edev is NULL and # we oops. # # We never had explicit support for EEH for those virtual devices. # Instead, EEH events are reported to the (real) pci device and handled # by the cxl driver. Which can then forward to the virtual devices and # handle dependencies. The fact that we try adding EEH support for the # virtual devices is new and a side-effect of the recent cleanup. # # This patch fixes it by skipping adding EEH support on powernv for # devices which don't have a pci_dn structure. # # The cxl driver doesn't create virtual devices on pseries so this patch # doesn't fix it there intentionally. # # Fixes: b905f8cdca77 ("powerpc/eeh: EEH for pSeries
