If anyone has any objections, please let me know. ------------------ From: Stefano Brivio commit 5c756065e47dc3e84b00577bd109f0a8e69903d7 upstream. Internal error codes happen to be positive, thus the PCI driver core won't treat them as failure, but we do. This would cause a crash later on as lpfc_pci_remove_one() is called (e.g. as shutdown function).
