Since\nthe RX channel was already submitted and issued prior to preparing\nthe TX descriptor, returning -EINVAL causes the SPI core to unmap the\nDMA buffers while the RX DMA engine continues writing to them, leading\nto potential memory corruption or use-after-free.\n\nTerminate the RX channel before returning on the TX prepare failure path.",
