Commit d698a388146c ("of: reserved-memory: ignore disabled memory-region nodes") added an early return in of_reserved_mem_device_init_by_idx(), but didn't call of_node_put() on a device_node whose ref-count was incremented in the call to of_parse_phandle() preceding the early exit.

Cc stable@ is used to assist in making sure your patch is backported to stable kernels, other than that the purpose Cc here is to indicate that specific people have been requested to comment on your patch.
So please skip these from the commit message in the future (for this one, wait and see if Rob is willing to trim them as he applies the patch).

Thanks for informing me of this, I've re-read the patch submission documentation and will omit the Cc's in the future from the commit message (other than Cc stable@).
Regards,
Chris.
