[PATCH 6.6 086/132] wifi: rtw89: ser: avoid multiple deinit on same CAM

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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

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

From: Zong-Zhe Yang <kevin_yang@xxxxxxxxxxx>

[ Upstream commit cea4066588308fa932b6b03486c608efff1d761c ]

We did deinit CAM in STA iteration in VIF loop. But, the STA iteration
missed to restrict the target VIF. So, if there are multiple VIFs, we
would deinit a CAM multiple times. Now, fix it.
