Subject: [PATCH 1/1] nvme: replace chan->device->dev with dmaengine_get_provider_device()
Date: Tue, 3 Nov 2026 16:28:37 -0500 [thread overview]
Message-ID: <20261103212837.1777874-1-Frank.Li@oss.nxp.com> (raw)
From: Frank Li <Frank.Li@nxp.com>
Use the dmaengine_get_provider_device() API instead of directly
accessing chan->device->dev to get the DMA provider device.
No functional change intended. Prepare make to struct dma_device private
to the DMA engine.
