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- 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.
