Subject: [PATCH v2 3/5] dmaengine: plx_dma: Don't set chancnt
Date: Sat, 15 Apr 2023 17:55:15 +0800 [thread overview]
Message-ID: <20230415095517.2763-4-jszhang@kernel.org> (raw)
In-Reply-To: <20230415095517.2763-1-jszhang@kernel.org>
The dma framework will calculate the dma channels chancnt, setting it
ourself is wrong.
