Subject[PATCH v2 linux-next] nvmem: meson-efuse: Replacing the use of of_node_put to __free
Date
Use __free for device_node values, and thus drop calls to
of_node_put.

The goal is to reduce memory management issues by using this
scope-based of_node_put() cleanup to simplify function exit
handling. When using __free a resource is allocated within a
block, it is automatically freed at the end of the block.

Changes since v2:
The patch was updated.
It was checked and there is a blank line after the last
variable declaration, it does not appear as an added line
because it already existed and it is not changed by these
changes.

Thanks
