Date: Sat, 24 Dec 2016 21:37:32 +0530 From: Bhumika Goyal <bhumirks@...il.com> To: julia.lawall@...6.fr, wim@...ana.be, linux@...ck-us.net, linux-watchdog@...r.kernel.org, linux-kernel@...r.kernel.org Cc: keescook@...omium.org, Bhumika Goyal <bhumirks@...il.com> Subject: [PATCH] drivers: watchdog: booke_wdt: add __ro_after_init to booke_wdt_info The object booke_wdt_info of watchdog_info structure is not modified after getting initialized by booke_wdt_init. Apart from getting referenced in init it is also stored in the info field of watchdog_device structure which is of type const struct watchdog_info *info. So, it becomes read only after init and therefore add __ro_after_init to it's declaration.
