dmaengine: move module_/dma_device_put() after route free (83c77940) · Commits · 戴 / test

We call dma_device_put() and module_put() after invoking .device_free_chan_resources callback, but we should also take care of router devices and invoke this after .route_free callback. So move it after .route_free Reviewed-by:
