pcmcia: avoid buffer overflow in pcmcia_setup_isa_irq
NR_IRQS may be as low as 16, causing a (harmless?) buffer overflow in pcmcia_setup_isa_irq(): static u8 pcmcia_used_irq[NR_IRQS]; ... if ((try < 32) && pcmcia_used_irq[irq]) continue; This is read-only, so if this address would be non-zero, it would just mean we would not attempt an IRQ >= NR_IRQS -- which would fail anyway! And as request_irq() fails for an irq >= NR_IRQS, the setting code path: pcmcia_used_irq[irq]++; is never reached as well.
