rtc: rework rtc_register_device() resource management

2020-11-19T11:50:12Z

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: goldfish: Enable interrupt in set_alarm() when necessary

2020-07-16T09:15:43Z

When use goldfish rtc, the "hwclock" command fails with "select() to /dev/rtc to wait for clock tick timed out". This is because "hwclock" need the set_alarm() hook to enable interrupt when alrm->enabled is true. This operation is missing in goldfish rtc (but other rtc drivers, such as cmos rtc, enable interrupt here), so add it.

rtc: goldfish: Use correct return value for goldfish_rtc_probe()

2020-05-30T02:12:34Z

When call function devm_platform_ioremap_resource(), we should use IS_ERR() to check the return value and return PTR_ERR() if failed. Signed-off-by: Tiezhu Yang Signed-off-by: Alexandre Belloni Link: https://lore.kernel.org/r/1590370788-15136-1-git-send-email-yangtiezhu@loongson.cn
