Please drop this include. Even if there was a usage of a *_device_id
this would be wrong.

unusual indention, please align the continuation line to the opening (.

I would expect that this declaration is added in the same commit as the
actual function.

Please make the alignment here consistent. Either align all members or
none, but not this mixture. My preference would be a single space
because these alignments tend to get annoying when they are kept during
future changes or diverge even more. Same for a few further struct
definitions further down this file.
