* rtc: rework rtc_register_device() resource managementBartosz Golaszewski2020-11-191-1/+1
| | | | | | | | | | | | | | | | | | | | 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.

* rtc: stop validating rtc_time after rtc_time_to_tmAlexandre Belloni2018-03-011-1/+1
| | | | | | | rtc_time_to_tm never generates an invalid tm. It is not necessary to validate it. Signed-off-by: Alexandre Belloni <alexandre.belloni@bootlin.com>
* rtc: sparc: make starfire explicitly non-modularPaul Gortmaker2016-11-041-6/+4
| | | | | | | | | | | | | | | | | | | | | | | The Kconfig currently controlling compilation of this code is: drivers/rtc/Kconfig:config RTC_DRV_STARFIRE drivers/rtc/Kconfig: bool "Starfire RTC" ...meaning that it currently is not being built as a module by anyone. Lets remove the couple traces of modular infrastructure use, so that when reading the driver there is no doubt it is builtin-only. We delete the MODULE_LICENSE tag etc. since all that information was (or is now) contained at the top of the file in the comments.

| | | | | | | | | | After the switch to devm_* functions and the removal of rtc_device_unregister(), the 'remove' function does not do anything. Delete it.
