[PATCH v2 6/7] powerpc/eeh: Replace device_node with pci_dn in eeh_ops
Gavin Shan
gwshan at linux.vnet.ibm.com
Tue Mar 17 16:15:07 AEDT 2015
There are 3 EEH operations whose arguments contain device_node:
read_config(), write_config() and restore_config(). The patch
replaces device_node with pci_dn.
