From 6c368932f0d885e54b8af06d699b6d559e86f0cd Mon Sep 17 00:00:00 2001 From: Bhumika Goyal Date: Mon, 26 Dec 2016 22:35:11 +0530 Subject: [PATCH] watchdog: constify watchdog_info structures Declare watchdog_info structures as const as they are only stored in the info field of watchdog_device structures. This field is of type const struct watchdog_info *, so watchdog_info structures having this property can be declared const too.
