Haojian,
I've updated the patch as follows, changes:
1. out_current --> output_current
2. output_current will be set only once during probe - we don't need to
adjust it every time backlight is changed, right?
3. and thus removing the out_current field within da903x_backlight_data
Please help review and verify, thanks.
