6.6-stable review patch. If anyone has any objections, please let me know.

From: Nuno Sa nuno.sa@analog.com
commit 1bc31444209c8efae98cb78818131950d9a6f4d6 upstream.
We need to first free the IRQ before calling of_dma_controller_free(). Otherwise we could get an interrupt and schedule a tasklet while removing the DMA controller.
