[PATCH 6/7] ALSA: us122l: constify usb_device_id.

From: Arvind Yadav
Date: Sun Aug 06 2017 - 02:49:37 EST


usb_device_id are not supposed to change at runtime. All functions
working with usb_device_id provided by <linux/usb.h> work with
const usb_device_id. So mark the non-const structs as const.
