From 8c9ad508c8737ca46a4c55b1062d159b86f7cee2 Mon Sep 17 00:00:00 2001 From: Sergey Vlasov Date: Mon, 14 Nov 2005 20:30:50 +0300 Subject: [PATCH] PCIE: make bus_id for PCI Express devices unique The bus_id string must be unique for all devices of that bus in the system, not just for devices with the same parent - otherwise multiple symlinks with identical names appear in /sys/bus/pci_express/devices.
