[PATCH 1/1] async_tx: replace direct ->device_prep*() calls with standard DMA engine API
From: Frank . Li
Date: Thu Sep 17 2026 - 19:54:22 EST
From: Frank Li <Frank.Li@xxxxxxx>
DMA engine consumers must not call the channel's device_prep_*() function
pointers directly. Use the standard dmaengine wrapper APIs instead.
