Subject: PCI: aardvark: Simplify initialization of rootcap on virtual bridge
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=cc890665eaa12a5cc7f772023eb53955a834f127;p=linux.git
PCI: aardvark: Simplify initialization of rootcap on virtual bridge
commit 454c53271fc11f3aa5e44e41fd99ca181bd32c62 upstream.
PCIe config space can be initialized also before pci_bridge_emul_init()
call, so move rootcap initialization after PCI config space initialization.
This simplifies the function a little since it removes one if (ret < 0)
check.
