From fdcfd854333be5b30377dc5daa9cd0fa1643a979 Mon Sep 17 00:00:00 2001 From: Bartosz Golaszewski Date: Mon, 9 Nov 2020 17:34:08 +0100 Subject: rtc: rework rtc_register_device() resource management rtc_register_device() is a managed interface but it doesn't use devres by itself - instead it marks an rtc_device as "registered" and the devres callback for devm_rtc_allocate_device() takes care of resource release. This doesn't correspond with the design behind devres where managed structures should not be aware of being managed. The correct solution here is to register a separate devres callback for unregistering the device. While at it: rename rtc_register_device() to devm_rtc_register_device() and add it to the list of managed interfaces in devres.rst. This way we can avoid any potential confusion of driver developers who may expect there to exist a corresponding unregister function.
