There are some more codes that contain isa_pic. Maybe worth an additional check.
./hw/i386/x86.c:573: intno = pic_read_irq(isa_pic);
./hw/intc/i8259.c:58:DeviceState *isa_pic;
./hw/intc/i8259.c:429: isa_pic = dev;
./hw/intc/apic.c:387: } else if (!apic_accept_pic_intr(dev) ||
!pic_get_output(isa_pic)) {
./hw/intc/apic.c:562: if (!apic_accept_pic_intr(dev) ||
!pic_get_output(isa_pic)) {
./hw/intc/apic.c:615: return isa_pic != NULL;
./hw/intc/ioapic.c:78: info->vector = pic_read_irq(isa_pic);
./hw/hppa/pci.c:67: return pic_read_irq(isa_pic);
./hw/mips/gt64xxx_pci.c:777: val = pic_read_irq(isa_pic);
./hw/alpha/pci.c:70: return pic_read_irq(isa_pic);
