checkpatch.pl will tell us this comment block should be

/* ULLI :
 * ID found in rtw8822bu sources
 */

But, I think we can just "/* ULLI: ID found in rtw8822bu sources */" 
if we really want to keep this comment.

rtw8821cu.h and rtw8822bu.h define this too.
Can we move it to usb.h?

The code here looks ridiculously wrong.

Should there be a rtw8723du_efuse struct and an union here?

BTW I found that Ulli's rtw88-usb repo has the same error, but I doubt
whether 8723du support is tested there.
