Merge tag 'rtc-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC updates from Alexandre Belloni:
 "This cycle, there were mostly non urgent fixes in drivers. I also
  finally unexported the non managed registration.

  Subsystem:

   - non devm managed registration is now removed from the driver API

   - all the unnecessary rtc_valid_tm() calls have been removed

  Drivers:

   - abx80X: watchdog support

   - cmos: fix non ACPI support

   - sc27xx: fix alarm support

   - Remove a possible sysfs race condition for ab8500, ds1307, ds1685,
     isl1208

   - Fix a possible race condition where an irq handler may be called
     before the rtc_device struct is allocated for mt6397, pl030,
     menelaus, armada38x"
