From 210762268466634ddbfaddb48fdf5181ce4b5f2d Mon Sep 17 00:00:00 2001 From: Stefan Richter Date: Sat, 27 Aug 2011 18:53:03 +0200 Subject: firewire: move fw_device reference counting from drivers to core fw_unit device drivers invariably need to talk to the fw_unit's parent (an fw_device) and grandparent (an fw_card). firewire-core already maintains an fw_card reference for the entire lifetime of an fw_device. Likewise, let firewire-core maintain an fw_device reference for the entire lifetime of an fw_unit so that fw_unit drivers don't have to.
