Subject: [PATCH] net: dm9051: Fix missing dev_kfree_skb() in dm9051_loop_rx()
Date: Mon, 21 Nov 2022 03:32:26 +0000 [thread overview]
Message-ID: <20221121033226.91461-1-yuancan@huawei.com> (raw)
The dm9051_loop_rx() returns without release skb when dm9051_stop_mrcmd()
returns error, free the skb to avoid this leak.
Fixes: 2dc95a4d30ed ("net: Add dm9051 driver")
Signed-off-by: Yuan Can <yuancan@huawei.com>
