Subject: [PATCH v3 1/5] dmaengine: dw-axi-dmac: Don't set chancnt
Date: Sun, 21 May 2023 18:02:48 +0800	[thread overview]
Message-ID: <20230521100252.3197-2-jszhang@kernel.org> (raw)
In-Reply-To: <20230521100252.3197-1-jszhang@kernel.org>

The dma framework will calculate the dma channels chancnt, setting it
ourself is wrong.
