Ok, so using the pointer to inside a specific pSettings field is fine.

But can you also explain to me why that insane driver does this:

	 static irqreturn_t UartInterrupt(int irq, void *dev_id)
	 {
	-       int irqno = (int)(unsigned long) dev_id;
	+       unsigned short *irqno = dev_id;
		...
		*irqno, dev_id);

instead of just ignoring "dev_id" entirely, and then just using that "irq" 
argument directly?
