Mohammed Shafi Shajakhan 61e1b0b00c ath9k: Fix kernel panic in AR2427 ... Kernel panic occurs just after AR2427 establishes connection with AP. Unless aggregation is enabled we don't initialize the TID structure. Thus accesing the elements of the TID structure when aggregation is disabled, leads to NULL pointer dereferencing.
