[PATCH 1/5] nvmem: core: Fix a resource leak on error in nvmem_add_cells_from_of()

[Srinivas Kandagatla]

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

This doesn't call of_node_put() on the error path so it leads to a
memory leak.

Fixes: 0749aa25af82 ("nvmem: core: fix regression in of_nvmem_cell_get()")
