commit 5dba51754b04a941a1064f584e7a7f607df3f9bc upstream.
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.
