Using the 2nd line of a .[ch] file does not follow the documented mechanisms. Documentation/process/license-rules.rst-1. Placement: Documentation/process/license-rules.rst- Documentation/process/license-rules.rst- The SPDX license identifier in kernel files shall be added at the first Documentation/process/license-rules.rst: possible line in a file which can contain a comment. For the majority Documentation/process/license-rules.rst: of files this is the first line, except for scripts which require the Documentation/process/license-rules.rst: '#!PATH_TO_INTERPRETER' in the first line. For those scripts the SPDX Documentation/process/license-rules.rst: identifier goes into the second line.
