Subject: [PATCH v11 1/5] PCI: Conditionally initialize host bridge native_* members
Date: Mon, 26 Oct 2020 19:57:04 -0700 [thread overview]
Message-ID: <fcbe8a624166a1101a755edfef44a185d32ff493.1603766889.git.sathyanarayanan.kuppuswamy@linux.intel.com> (raw)
In-Reply-To: <cover.1603766889.git.sathyanarayanan.kuppuswamy@linux.intel.com>
In-Reply-To: <cover.1603766889.git.sathyanarayanan.kuppuswamy@linux.intel.com>
If CONFIG_PCIEPORTBUS is not enabled in kernel then initialing
struct pci_host_bridge PCIe specific native_* members to "1" is
incorrect. So protect the PCIe specific member initialization
with CONFIG_PCIEPORTBUS.
