-Subject: [PATCH] nvmem: core: fix device node refcounting
-
-In of_nvmem_cell_get(), of_get_next_parent() is used on cell_np. This
-will decrement the refcount on cell_np, but cell_np is still used later
-in the code. Use of_get_parent() instead and of_node_put() in the
-appropriate places.

-Fixes: 69aba7948cbe ("nvmem: Add a simple NVMEM framework for consumers")
-Fixes: 7ae6478b304b ("nvmem: core: rework nvmem cell instance creation")
