Subject: [PATCH v9 1/5] PCI: Conditionally initialize host bridge native_* members
Date: Fri, 18 Sep 2020 12:58:30 -0700	[thread overview]
Message-ID: <a640e9043db50f5adee8e38f5c60ff8423f3f598.1600457297.git.sathyanarayanan.kuppuswamy@linux.intel.com> (raw)
In-Reply-To: <cover.1600457297.git.sathyanarayanan.kuppuswamy@linux.intel.com>

From: Kuppuswamy Sathyanarayanan <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.
