Subject: [PATCH 05/10] wifi: ath12k: ath12k_mac_station_add(): fix potential rx_stats leak
Date: Tue, 26 Nov 2024 19:11:34 +0200	[thread overview]
Message-ID: <20241126171139.2350704-6-kvalo@kernel.org> (raw)
In-Reply-To: <20241126171139.2350704-1-kvalo@kernel.org>

From: Rameshkumar Sundaram <quic_ramess@quicinc.com>

If peer creation fails ar->rx_stats needs to be freed in error handling.

Tested-on: QCN9274 hw2.0 PCI WLAN.WBE.1.3.1-00173-QCAHKSWPL_SILICONZ-1
Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0.c5-00481-QCAHMTSWPL_V1.0_V2.0_SILICONZ-3
