From ffa6a7054d172a2f57248dff2de600ca795c5656 Mon Sep 17 00:00:00 2001 From: Cornelia Huck Date: Wed, 4 Mar 2009 12:44:00 +0100 Subject: Driver core: Fix device_move() vs. dpm list ordering, v2 dpm_list currently relies on the fact that child devices will be registered after their parents to get a correct suspend order. Using device_move() however destroys this assumption, as an already registered device may be moved under a newly registered one. This patch adds a new argument to device_move(), allowing callers to specify how dpm_list should be adapted.
