X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=011e29e7d93d80c2529ba17109bc4e5d031ea2b1;p=linux.git watchdog: cadence_wdt: make of_device_ids const. of_device_ids are not supposed to change at runtime. All functions working with of_device_ids provided by <linux/of.h> work with const of_device_ids. So mark the non-const structs as const.
