From 6a73336bde293741026614135419e9b76afb9145 Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Fri, 12 Sep 2014 08:50:10 -0600 Subject: [PATCH] PCI: Remove "no hotplug settings from platform" warning We print way too many messages like this: pci 0000:00:00.0: no hotplug settings from platform pci 0000:00:00.0: using default PCI settings This usually happens when the platform doesn't supply an ACPI _HPP method, but the method is optional, so there's no point in warning about it. Not only are the messages useless, but we call pci_configure_slot() far too many times, so they're repeated many times. I'll fix the overuse of pci_configure_slot() too, but that will wait until the next merge window. For now, just remove both log messages.
