From 3774e02c742973c3fb343e8626f34041548ad5c7 Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Wed, 11 Jan 2017 00:02:54 +0530 Subject: [PATCH] usb: isp1760: constify usb_gadget_ops structures Declare usb_gadget_ops structures as const as they are only stored in the ops field of a usb_gadget structure. This field is of type const, so usb_gadget_ops structures having this property can be declared const too.
