net: usb: cdc-phonet: constify usb_device_id

ArvindYadavCs · davem330 · commit 7f04c61d91c8 · 2017-08-08T17:47:58.000-07:00
usb_device_id are not supposed to change at runtime. All functions
working with usb_device_id provided by &lt;linux/usb.h&gt; work with
const usb_device_id. So mark the non-const structs as const.
