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()"

If you say yes here you get support for the Ingenic JZ47xx SoCs RTC
controllers.
This driver can also be buillt as a module. If so, the module
will be called rtc-jz4740.
