Subject: [PATCH 4/5] ath11k: Fix memory leak in ath11k_qmi_driver_event_work
Date: Mon, 13 Sep 2021 21:02:45 +0300 [thread overview]
Message-ID: <20210913180246.193388-4-jouni@codeaurora.org> (raw)
In-Reply-To: <20210913180246.193388-1-jouni@codeaurora.org>
From: Baochen Qiang <bqiang@codeaurora.org>
The buffer pointed to by event is not freed in case
ATH11K_FLAG_UNREGISTERING bit is set, resulting in
memory leak, so fix it.
Tested-on: WCN6855 hw2.0 PCI WLAN.HSP.1.1-01720.1-QCAHSPSWPL_V1_V2_SILICONZ_LITE-1
Fixes: d5c65159f289 ("ath11k: driver for Qualcomm IEEE 802.11ax devices")
