[PATCH] acpi/video: lcd_get_level_current doen't return current level

[Artem Savkov]

acpi_video_device_lcd_get_level_current() called acpi_video_bqc_value_to_level()
with "*level" as a second argument, resulting in level being returned based on
initial input, not current brightness, breaking backlight controls.
