module: fix comment style
Many comments in this module do not comply with the preferred multi-line comment style as reported by 'scripts/checkpatch.pl': WARNING: Block comments use * on subsequent lines WARNING: Block comments use a trailing */ on a separate line Fix those comments, along with (unreported for some reason?) the starts of the multi-line comments not being /* on their own line...
