From 5add99cfef416487d32b4b7075fe1a409f3a5e82 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Thu, 7 Nov 2013 01:41:39 +0100 Subject: ACPI / hotplug: Simplify device ejection routines Simplify handle_root_bridge_removal() and acpi_eject_store() by getting rid of struct acpi_eject_event and passing device objects directly to async routines executed via acpi_os_hotplug_execute().
