        don't need to since we only support one card but doing this will make it

        easier to upgrade the driver for multiple devices in the future.

If you want to share the IRQ with another device and the driver refuses to

do so, you might succeed with changing the DC390_IRQ type in tmscsim.c to 

SA_SHIRQ | SA_INTERRUPT.

IRQF_SHARED | IRQF_DISABLED.
