Luke,

As I've seen you use S-o-b tag a few times like this, do you actually mean 
Reviewed-by: tag which tells you've looked through the change and think 
it's good/useful for the kernel?

S-o-b relates to authorship of the code in the patch (and should be 
there right from the submission, not added like this).

This is not used?

Why is ASUS_WMI_DEVID_CAMERA_LED added here and into the .c file?

No, it does the same as CAMERA_LED but the values are opposite. I
thought it would just be useful as documentation of the WMI functions.

Should I remove it?

That was a mistake, I used it for testing.
