New Revision: 258758
URL: http://svnweb.freebsd.org/changeset/base/258758
Log:
Make sure any waiters on the scan results get notified if the scan task
decides to do nothing.
If this isn't done, then a scan request whilst a scan occurs in an active
channel set or a completed channel set will hang.
Tested:
* Intel 5100, STA mode
