Subject: [PATCH] nvmem: meson-efuse: Replacing the use of of_node_put to
|
|
__free
|
|
|
|
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.
