Subject: [PATCH v3 2/3] wcn36xx: Release DMA channel descriptor allocations
Date: Fri,  5 Nov 2021 12:21:51 +0000	[thread overview]
Message-ID: <20211105122152.1580542-3-bryan.odonoghue@linaro.org> (raw)
In-Reply-To: <20211105122152.1580542-1-bryan.odonoghue@linaro.org>

When unloading the driver we are not releasing the DMA descriptors which we
previously allocated.

Fixes: 8e84c2582169 ("wcn36xx: mac80211 driver for Qualcomm WCN3660/WCN3680 hardware")
Signed-off-by: Bryan O'Donoghue <bryan.odonoghue@linaro.org>
