From af8874491de6f03237df5e20d87324cbbe226f19 Mon Sep 17 00:00:00 2001 From: "Rafael J. Wysocki" Date: Sun, 16 Feb 2014 00:09:47 +0100 Subject: [PATCH] ACPI / dock: Associate dock platform devices with ACPI device objects To allow user space to check which ACPI device object the dock station is represented by, make acpi_dock_add() indicate to platform_device_register_full() which ACPI device object should be the companion of the new platform device. This also ensures that the ACPI device object in question will not go away while the dock platform device is present (which is always). Signed-off-by: Rafael J.
