Hi Marcel: > please fix the coding style. It is if[space](. Okay, I see. > I would say something similar in style > to what I have done for the older CSR chips. See workaround above. > And on that note, you could use data->udev to get the usb_device > struct ;) As to this point, since now we are not using the btusb to download the patch and radio table, I think we do not need to alloc the data struct and use data->udev before the workaround. So I'll still keep it was. How do you think it ? Thank you very much !
