Any set_lcd_level() call can fail for one of two reasons: either requested brightness is outside the allowed range or the ACPI method used for setting brightness level is not available. For bl_update_status(), the first case is handled by backlight core, which means bl_update_status() will not even be called if requested brightness is outside the allowed range. The second case will be logged anyway by set_lcd_level() itself, so there is no point in generating another message in bl_update_status(). Remove the superfluous debug message along with a local variable that is now redundant.
