Subject: watchdog: booke_wdt: add __ro_after_init to booke_wdt_info
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=8d97005e01445921b429e92d7c425a86f76050ab;p=openwrt%2Fstaging%2Fblogic.git

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.
