Title
clk: davinci: Add NULL check in davinci_lpsc_clk_register()
Summary
In the Linux kernel, the following vulnerability has been resolved:
clk: davinci: Add NULL check in davinci_lpsc_clk_register()
devm_kasprintf() returns NULL when memory allocation fails. Currently,
davinci_lpsc_clk_register() does not check for this case, which results
in a NULL pointer dereference.
Add NULL check after devm_kasprintf() to prevent this issue and ensuring
no resources are left allocated.

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.
