Subject: [PATCH 1/1] mfd: stm32-timers: use dmaengine_desc_set_callback()
Date: Mon, 2 Nov 2026 12:46:56 -0500 [thread overview]
Message-ID: <20261102174656.3939832-1-Frank.Li@oss.nxp.com> (raw)
From: Frank Li <Frank.Li@nxp.com>
Replace open-coded assignments to callback and callback_param fields
of struct dma_async_tx_descriptor with a call to the
dmaengine_desc_set_callback() helper.
No functional change intended. Prepare make to struct
dma_async_tx_descriptor private to the DMA engine.
