* rtc: Include <linux/kstrtox.h> when appropriateChristophe JAILLET2022-11-151-0/+1
| | | | | | | | | | | The kstrto<something>() functions have been moved from kernel.h to kstrtox.h. So, include the latter directly in the appropriate files.

* rtc: rework rtc_register_device() resource managementBartosz Golaszewski2020-11-191-2/+0
| | | | | | | | | | | | | | | | | | | | 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.
