Subject: [PATCH v3 10/11] ath9k: fix null pointer dereference in ani monitor code
|
|
|
|
In 'ath9k_ani_reset' the 'ahp->ah_curani' will be initialized only
|
|
if 'DO_ANI(ah)' true. In 'ath9k_hw_ani_monitor' we are using
|
|
'ahp->ah_curani' unconditionally, and it will cause a NULL pointer
|
|
dereference on AR9100.
