Merge tag 'rtc-4.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux

Pull RTC fix from Alexandre Belloni:
 "A single fix for this cycle. It is worth taking it for 4.10 so that
  distributions will not have CONFIG_RTC_DRV_JZ4740 switching from m to
  y in their config.

  Summary:
   - Allow jz4740 to build as a module again by using kernel_halt()"
