[01/12] Staging: batman-adv: checkpatch cleanup of comments
Commit Message
checkpatch now detects the start of a comment and warns about usage of
multiple spaces at the beginning of a line. We have to replace the ' '
in multiple lines comments by ' * ' to fix it.
Checkpatch also wants a comment after a definition of a spinlock_t which
describes what it protects. It is currently not possible to add it
before the actual struct which includes the spinlock.
