From 0a1e1b26f560411cb58066201dddad5c224e8b9e Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 21 Nov 2016 11:30:45 -0600 Subject: [PATCH] PCI/PME: Drop unused support for PMEs from Root Complex Event Collectors Since we register pcie_pme_driver only for PCI_EXP_TYPE_ROOT_PORT, the PME driver never claims Root Complex Event Collectors. Remove unused code related to Root Complex Event Collectors. Signed-off-by: Bjorn Helgaas Acked-by: Rafael J.
