Subject: [PATCH 6/8] Input: synaptics_usb: constify usb_device_id.
Date: Sun, 6 Aug 2017 13:11:25 +0530 [thread overview]
Message-ID: <1502005287-17705-7-git-send-email-arvind.yadav.cs@gmail.com> (raw)
In-Reply-To: <1502005287-17705-1-git-send-email-arvind.yadav.cs@gmail.com>
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.
