Subject: [PATCH 3.18 08/23] net/sonic: Use dma_mapping_error()
Date: Tue, 10 Jul 2018 20:24:41 +0200 [thread overview]
Message-ID: <20180710182309.230532185@linuxfoundation.org> (raw)
In-Reply-To: <20180710182308.877332304@linuxfoundation.org>
3.18-stable review patch. If anyone has any objections, please let me know.
------------------
From: Finn Thain <fthain@telegraphics.com.au>
[ Upstream commit 26de0b76d9ba3200f09c6cb9d9618bda338be5f7 ]
With CONFIG_DMA_API_DEBUG=y, calling sonic_open() produces the
message, "DMA-API: device driver failed to check map error".
Add the missing dma_mapping_error() call.
