From afeb12b7478fee31888e7c34804bee2f658e7765 Mon Sep 17 00:00:00 2001 From: Randy Dunlap Date: Wed, 29 Oct 2008 14:13:20 -0700 Subject: fujitsu-laptop: fix section mismatch warning Could fix a bug in a hotplug add scenario. WARNING: drivers/misc/fujitsu-laptop.o(.text+0xbde): Section mismatch in reference from the function acpi_fujitsu_add() to the variable .init.data:fujitsu_dmi_table The function acpi_fujitsu_add() references the variable __initdata fujitsu_dmi_table. This is often because acpi_fujitsu_add lacks a __initdata annotation or the annotation of fujitsu_dmi_table is wrong.

The application panel contains the following keys: lock, mobility center, eco, info. Whilst key 4 might be more appropriate for help then key 2, I've done things the S6410 way. I can confirm that backlight control is functional, and that the lock key activates the Gnome screensaver as expected.
