[PATCH 14/36] PCI: convert class code to use dev_groups

From: Greg Kroah-Hartman
Date: Wed Jul 24 2013 - 18:07:43 EST


The dev_attrs field of struct class is going away soon, dev_groups
should be used instead. This converts the PCI class code to use the
correct field.

Bjorn, feel free to take this through your tree, or ACK it and I can take it
