Without this, the code succeeds when the port is opened by root and we get unwanted interrupts storm on the first key stroke. Instead of that, tell the user we failed and that we won't continue. I suppose, the code was copied from the serial layer where we may want to change the irq number, so we must allow open even of the failing port. This is not the case for this driver at all.
