Subject: [PATCH 1/1] PCI: replace chan->device->dev with dmaengine_get_provider_device()
Date: Tue, 3 Nov 2026 16:29:20 -0500 [thread overview]
Message-ID: <20261103212924.1780217-1-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. Prepare make to struct dma_device private to the DMA
engine.
Assisted-by: LLM
