Man, how many incarnations of this driver are there? It's really about time
to mainline it.

Modulo the IDs posted by Nick Morrow already only this one is missing:

	{USB_DEVICE_AND_INTERFACE_INFO(0x2001, 0x331f, 0xff, 0xff, 0xff),
	  .driver_info = (kernel_ulong_t)&(rtw8822b_hw_spec)}, /* Dlink - DWA-183 D Ver */

Will add it for the next round.

Thanks,
  Sascha
