Those inline are not needed at all:
- pseries_eeh_init_edev_recursive() is only called from files build wich 
CONFIG_HOTPLUG_PCI_RPA which depends on CONFIG_PSERIES and CONFIG_EEH
- pseries_eeh_init_edev() is used exclusively in
arch/powerpc/platforms/pseries/eeh_pseries.c and should be made static.

Can you update your patch ?

Thanks
Christophe
