[rtc-linux] [PATCH] rtc: armada38x: add __ro_after_init to armada38x_rtc_ops

[Bhumika Goyal <bhumirks@gmail.com>]

The object armada38x_rtc_ops of type rtc_class_ops structure is not
modified after getting initialized by armada38x_rtc_probe. Apart from
getting referenced in init it is also passed as an argument to the function
devm_rtc_device_register but this argument is of type const struct
rtc_class_ops *. Therefore add __ro_after_init to its declaration.
