[PATCH 10/16] powerpc: vio: use dev_groups and not dev_attrs for bus_type

From: Greg Kroah-Hartman
Date: Tue Jun 06 2017 - 15:24:57 EST


The dev_attrs field has long been "depreciated" and is finally being
removed, so move the driver to use the "correct" dev_groups field
instead for struct bus_type.
