Subject: watchdog: s3c2410: Constify local structures
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=58415efe96670b858eb7b5ab066881ae3f1dad25;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

watchdog: s3c2410: Constify local structures

Structures watchdog_device, watchdog_ops and s3c2410_wdt_variant are not
modified so they can be made const to increase code safeness.
