    Subject[PATCH 3.12 096/170] mac80211: fix IBSS join by initializing last_scan_completed
    Date
    From: Krzysztof Hałasa <khalasa@piap.pl>

    3.12-stable review patch. If anyone has any objections, please let me know.

    ===============

    commit c7d37a66e345df2fdf1aa7b2c9a6d3d53846ca5b upstream.

    Without this fix, freshly rebooted Linux creates a new IBSS
    instead of joining an existing one. Only when jiffies counter
    overflows after 5 minutes the IBSS can be successfully joined.
