Messages in this thread Patch in this message | | | From | MarileneGarcia <> | Subject | [PATCH v2 linux-next] nvmem: meson-efuse: Replacing the use of of_node_put to __free | Date | Wed, 15 May 2024 23:28:38 -0300 |
| |
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
