rtc: ab-eoz9: fix abeoz9_rtc_read_alarm abeoz9_rtc_read_alarm assumes we always read the alarm in 12-hour mode while abeoz9_rtc_set_alarm will always set it in 24-hour mode. We could support 12-hour mode in both functions but it seems very unlikely that the RTC would be set to 12-hour mode now as the driver has been setting it to 24-hour mode for a while now. The setting is undefined at power-up and unchanged by subsequent resets which doesn't help us.

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.

rtc: Use named initializers for arrays of i2c_device_data While being less compact, using named initializers allows to more easily see which members of the structs are assigned which value without having to lookup the declaration of the struct. And it's also more robust against changes to the struct definition. The mentioned robustness is relevant for a planned change to struct i2c_device_id that replaces .driver_data by an anonymous union. While touching all these arrays, unify usage of whitespace and commas. This patch doesn't modify the compiled arrays, only their representation in source form benefits. The former was confirmed with x86 and arm64 builds.

rtc: ab-eoz9: add missing MODULE_DEVICE_TABLE() The driver has a match table for the i2c bus wired into its driver structure, but the table is not exported with MODULE_DEVICE_TABLE(). Add the missing MODULE_DEVICE_TABLE() entry so module alias information is generated for automatic module loading. This is a source-level fix. It does not claim dynamic hardware reproduction; the evidence is the driver-owned match table, its use by the driver registration structure, and the missing module alias publication.
