Subject: watchdog: pika_wdt: add __ro_after_init to ident
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cb5f9d406d50fc01c6564956ed9317614e665208;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

watchdog: pika_wdt: add __ro_after_init to ident

The object ident of type watchdog_info structure is not
modified after getting initialized by pikawdt_init. Apart from getting
referenced in init it is also passed as an argument to the function
copy_to_user but this argument is of type const void *. Therefore add
__ro_after_init to its declaration.
