Modified Files:
src/sys/arch/zaurus/dev: lcdctl.c scoop.c
Log Message:
Allow calling scoop_set_backlight() even before scoop is attached and
schedule initial values in that case as ioexp does. Suggested by nonaka@.
Now lcdctl no longer has to defer lcdctl_set_brightness() by
config_finalize_register(9), which is a bit too late.
(i.e. no backlight during USB/SD probe by config_interrupt(9) in previous)
