[PATCH 3/3] powerpc/eeh: Display eeh error location for bus and device (resend)

[Richard A Lary]

From: Richard A Lary <rlary at linux.vnet.ibm.com>

  For adapters which have devices under a PCIe switch/bridge it is informative
  to display information for both the PCIe switch/bridge and the device on
  which the bus error was detected.
