[PATCH 3.13 053/198] mac80211: fix IBSS join by initializing last_scan_completed

From: Kamal Mostafa
Date: Tue Jul 15 2014 - 17:41:17 EST


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

------------------

From: =?UTF-8?q?Krzysztof=20Ha=C5=82asa?= <khalasa@xxxxxxx>

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.
