Updated patch below.

Adrian
<-- snip -->
This patch contains the following possible cleanups:
- make the following needlessly global code static:
- adb.c: adb_controller
- adb.c: adb_init()
- adbhid.c: adb_to_linux_keycodes[] (also make it const)
- via-pmu68k.c: backlight_level
- via-pmu68k.c: backlight_enabled
- remove the following unused code:
- via-pmu68k.c: sleep_notifier_list
