Please, don't mix different logical changes on the same patch. If you have
more than one change to do, send it as a patch set.

This were fixed on another patch. I think that the patch is already upstream.

Ideally, the above should be on two separate patches, one adding the new USB IDs and
the other one converting the structure to use the new way. That makes easier for reviewers
to see what changed on each patch.

Don't use // comments. Did you ran scripts/checkpatch.pl? It should have warned you
that the above syntax is not allowed.

The above code is a separate patch. Btw, for each patch, you should add a description
saying why the change is needed.

This should be a separate patchset as well, as it adds support for a new device variant.
