Before detecting the cable type on the dma bar, the driver should check whether the 'bmdma_addr' is zero, which means the adapter does not support DMA, otherwise we will get the following error:

I fixed that and applied to for-5.18-fixes. Thanks.
I completely overlooked that this needs a CC stable...
