Ben Dooks 54aa6c4936 dmaengine: dw-axi-dmac: ignore interrupt if no descriptor ... [ Upstream commit 820f5ce999 ] If the channel has no descriptor and the interrupt is raised then the kernel will OOPS. Check the result of vchan_next_desc() in the handler axi_chan_block_xfer_complete() to avoid the error happening.
