The new support for nvmem devices from the rtc layer caused a build

'ERR_PTR' [-Werror=implicit-function-declaration]
This adds the missing include to ensure we can always include
the header.

I'd suggest adding this patch in the rtc tree on top of the
nvmem support there.
Thanks for the patch, we would need similar patch for
include/linux/nvmem-consumer.h too.
