From b844eba292b477cda14582bfc6f535deed57a82d Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 23 Mar 2008 20:28:24 +0100 Subject: PM: Remove destroy_suspended_device() After 2.6.24 there was a plan to make the PM core acquire all device semaphores during a suspend/hibernation to protect itself from concurrent operations involving device objects. That proved to be too heavy-handed and we found a better way to achieve the goal, but before it happened, we had introduced the functions device_pm_schedule_removal() and destroy_suspended_device() to allow drivers to "safely" destroy a suspended device and we had adapted some drivers to use them. Now that these functions are no longer necessary, it seems reasonable to remove them and modify their users to use the normal device unregistration instead. Signed-off-by: Rafael J.
