Title
drm/logicvc: Fix device node reference leak in logicvc_drm_config_parse()
Summary
In the Linux kernel, the following vulnerability has been resolved:
drm/logicvc: Fix device node reference leak in logicvc_drm_config_parse()
The logicvc_drm_config_parse() function calls of_get_child_by_name() to
find the "layers" node but fails to release the reference, leading to a
device node reference leak.
Fix this by using the __free(device_node) cleanup attribute to automatic
release the reference when the variable goes out of scope.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the
vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base
model, served locally by ML-Gateway.
They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
