From 42ee4194f2ac7ff16f8e5cb7900c7d35d483f974 Mon Sep 17 00:00:00 2001 From: Laszlo Ersek Date: Thu, 10 Apr 2014 10:24:37 +0200 Subject: pci-assign: accept Error from pci_add_capability2() Propagate any errors while adding PCI capabilities to assigned_device_pci_cap_init(). We'll continue the propagation upwards when assigned_device_pci_cap_init() becomes a leaf itself (when none of its callees will report errors internally any longer when detecting and returning them).
