> Betreff: [PATCH] leds-ot200: Fix error caused by shifted mask
> 
> During the development of this driver an in-house register documentation
> was used. The last weeks some integration tests were done and this problem
> was found. It turned out that the released register documentation is wrong.
> 
> The fix is very simple: shift all masks by one.
