So, this is an updated version following
the right way of writing change logs while
making sure the signed-off-by mismatch is fixed.

The test file for the IR decoder used single-line comments
at the top to document its purpose and licensing,
which is inconsistent with the style used throughout the
Linux kernel.

In this patch i converted the file header to
a proper multi-line comment block
(/*) that aligns with standard kernel practices.
This improves readability, consistency across selftests,
and ensures the license and documentation are
clearly visible in a familiar format.

No functional changes have been made.

I don't think this patch is necessary. We have files that use // style
comments. How did you find this issue.
