Subject: [PATCH 10/16 v2] powerpc: vio: use dev_groups and not dev_attrs for bus_type

From: Greg Kroah-Hartman <[email-masked]>
Date: Wed, 7 Jun 2017 10:58:46 +0200

From: Greg Kroah-Hartman <[email-masked]>

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.
