Subject: [RFC 4/7] x86/PCI: Rename struct pci_sysdata as struct pci_controller
Date: Tue, 7 Apr 2015 12:31:09 +0800 [thread overview]
Message-ID: <1428381072-27486-5-git-send-email-jiang.liu@linux.intel.com> (raw)
In-Reply-To: <1428381072-27486-1-git-send-email-jiang.liu@linux.intel.com>
Rename struct pci_sysdata as struct pci_controller, so we could share
common code between IA64 and x86 later.
Signed-off-by: Jiang Liu <jiang.liu@linux.intel.com>
