Subject: [PATCH 4.9 35/97] tty: serial: imx: use the sg count from dma_map_sg
Date: Wed, 22 Jan 2020 10:28:39 +0100 [thread overview]
Message-ID: <20200122092802.178322001@linuxfoundation.org> (raw)
In-Reply-To: <20200122092755.678349497@linuxfoundation.org>
From: Peng Fan <peng.fan@nxp.com>
commit 596fd8dffb745afcebc0ec6968e17fe29f02044c upstream.
The dmaengine_prep_slave_sg needs to use sg count returned
by dma_map_sg, not use sport->dma_tx_nents, because the return
value of dma_map_sg is not always same with "nents".
Fixes: b4cdc8f61beb ("serial: imx: add DMA support for imx6q")
