helm-chart/csi-driver/templates/daemonset.yaml:20

• Review the YAML indentation for the podAnnotations block to ensure that it aligns correctly within the metadata section; inconsistent indentations can lead to YAML parsing issues.

helm-chart/csi-driver/templates/csi-linode-controller.yaml:22

• Verify that the indentation and structure of the podAnnotations block is consistent with the labels block to maintain readability and prevent formatting issues.
