Subject: [PATCH 4.4 02/38] atm: nicstar: Unmap DMA on send error
Date: Mon, 23 Nov 2020 13:21:48 +0100 [thread overview]
Message-ID: <20201123121804.434822607@linuxfoundation.org> (raw)
In-Reply-To: <20201123121804.306030358@linuxfoundation.org>
From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
[ Upstream commit 6dceaa9f56e22d0f9b4c4ad2ed9e04e315ce7fe5 ]
The `skb' is mapped for DMA in ns_send() but does not unmap DMA in case
push_scqe() fails to submit the `skb'. The memory of the `skb' is
released so only the DMA mapping is leaking.
Unmap the DMA mapping in case push_scqe() failed.
Fixes: 864a3ff635fa7 ("atm: [nicstar] remove virt_to_bus() and support 64-bit platforms")
