Jeremiah, I didn't make the special patch for the linux-next before, so I don't know why this patch is there and have issue. Based on current code in the linux-next, I made below patch to fix this issue. Could you please try again with attached patch fix.

The root cause of this issue is that the cyapa->irq has been removed but still used in the driver.
