This contains the following 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 Signed-off-by: Adrian Bunk <bunk@kernel.org> Acked-by: Geert Uytterhoeven <geert@linux-m68k.org> Acked-by: Stephen Rothwell <sfr@canb.auug.org.au> Signed-off-by: Paul Mackerras <paulus@samba.org>
