svn commit: r218091 - head/sys/net80211

[Bernhard Schmidt]

Author: bschmidt

New Revision: 218091
URL: http://svn.freebsd.org/changeset/base/218091

Log:
  Change return code semantics of start_scan_locked(). Instead of reporting
  if a scan is running, report if a scan has been started. The return value
  itself is not (yet) used anywhere in the tree and it is also not exported
  to userspace.
