Title
dmaengine: dw-axi-dmac: ignore interrupt if no descriptor
Summary
In the Linux kernel, the following vulnerability has been resolved: dmaengine: dw-axi-dmac: ignore interrupt if no descriptor 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.
