From fe05725ff97530e26109a0c3d52cef7fff326e15 Mon Sep 17 00:00:00 2001 From: Yinghai Lu Date: Mon, 2 Apr 2012 18:31:53 -0700 Subject: [PATCH] x86/PCI: embed name into pci_root_info struct We now keep the pci_root_info struct for the entire lifetime of the host bridge, so just embed the name in the struct rather than allocating it separately.
