I tried move it earlyer, but without success:

static int __devinit pluto2_probe(struct pci_dev *pdev,
                                  const struct pci_device_id *ent)
{
        struct pluto *pluto;
        struct dvb_adapter *dvb_adapter;
        struct dvb_demux *dvbdemux;
        struct dmx_demux *dmx;
        int ret = -ENOMEM;
        u32 hodnota;

        pluto = kmalloc(sizeof(struct pluto), GFP_KERNEL);
        if (!pluto)
                goto out;

        memset(pluto, 0, sizeof(struct pluto));
        pluto->pdev = pdev;

pci_read_config_dword(pluto->pdev, 0x6c, &hodnota);
hodnota |= 0x8000;
pci_write_config_dword(pluto->pdev, 0x6c, hodnota);

I still gets:
PCI: Enabling device 0000:03:00.0 (0000 -> 0002)
ACPI: PCI interrupt 0000:03:00.0[A] -> GSI 10 (level, low) -> IRQ 10
PCI: Setting latency timer of device 0000:03:00.0 to 64
pluto2 0000:03:00.0: overflow irq (1)
many of these...
DVB: registering new adapter (pluto2).
pluto2 0000:03:00.0: board revision 15.255
pluto2 0000:03:00.0: MAC ff:ff:ff:ff:ff:ff
still many of these...
pluto2 0000:03:00.0: overflow irq (1)
pluto2 0000:03:00.0: overflow irq (1)
pluto2 0000:03:00.0: overflow irq (1)
pluto2 0000:03:00.0: overflow irq (1)
