Ian Abbott a4965d98b4 staging: comedi: comedi_isadma: Use a non-NULL device for DMA API ... The "comedi_isadma" module calls `dma_alloc_coherent()` and `dma_free_coherent()` with a NULL device pointer which is no longer allowed. If the `hw_dev` member of the `struct comedi_device` has been set to a valid device, that can be used instead. Unfortunately, all the current users of the "comedi_isadma" module leave the `hw_dev` member set to NULL. In that case, fall back to using the comedi "class" device pointed to by the `class_dev` member if that is non-NULL. In that case, make it "DMA-capable" with a coherent DMA mask set to the ISA bus limit of 16MB (24 bits).
