Subject: [PATCH v2 1/5] dmaengine: dw-axi-dmac: Don't set chancnt
Date: Sat, 15 Apr 2023 17:55:13 +0800 [thread overview]
Message-ID: <20230415095517.2763-2-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.
