There is not a real need to have this one in a separate patch. Also, it
depends on the patch "[PATCH] HID: cp2112: use proper hidraw name with
minor number", so better include this cp2112 in this series (as I
mentioned in the cp2112 patch).

I'd say simply squash this patch with 2/2 and have the cp2112 as 1/2.
