[PATCH V4 4/4] X86/PCI: Remove unnecessary 'quirk_amd_nb_node'

From: suravee.suthikulpanit
Date: Thu May 08 2014 - 12:45:52 EST


From: Myron Stowe <myron.stowe@xxxxxxxxxx>

The quirk is used for fixing up the numa_node information in sysfs for AMD hostbridge
devices (i.e. PCI device 00:[18-1f].x). However, this is currently unused.
and is becoming maintenance burden. Therefore, it is removed.
