Subject: [PATCH v8 1/5] PCI: Conditionally initialize host bridge native_* members
Date: Fri, 24 Jul 2020 20:58:52 -0700 [thread overview]
Message-ID: <8a76b4a524d3915d42e894da7f4dbdec6c104512.1595649348.git.sathyanarayanan.kuppuswamy@linux.intel.com> (raw)
In-Reply-To: <cover.1595649348.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.
