Subject: [PATCH AUTOSEL 4.14 04/17] NFC: st95hf: Fix memleak in st95hf_in_send_cmd
Date: Mon,  7 Sep 2020 12:34:47 -0400	[thread overview]
Message-ID: <20200907163500.1281543-4-sashal@kernel.org> (raw)
In-Reply-To: <20200907163500.1281543-1-sashal@kernel.org>

From: Dinghao Liu <dinghao.liu@zju.edu.cn>

[ Upstream commit f97c04c316d8fea16dca449fdfbe101fbdfee6a2 ]

When down_killable() fails, skb_resp should be freed
just like when st95hf_spi_send() fails.
