I recommend to leave these alone.
CODING_STYLE.rst:
Rationale: The // form is valid in C99, so this is purely a matter of
consistency of style. The checkpatch script will warn you about this.
For "real" comments, we overwhelmingly use /* */, and avoiding // makes
sense. Most exceptions are in code we copy from elsewhere, such as
disas/libvixl/.
For commenting out *code*, we use both forms. Here are the counts for
commenting out macro definitions:
$ git-grep '^/\* *# *define' | wc -l
125
$ git-grep '^// *# *define' | wc -l
192
