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()" * tag 'rtc-4.10-2' of git://git.kernel.org/pub/scm/linux/kernel/git/abelloni/linux: rtc: jz4740: make the driver buildable as a module again
