The current code is:


/* search for all Adatpec I2O RAID cards */
while ((pDev = pci_get_device( PCI_DPT_VENDOR_ID, PCI_ANY_ID, pDev))) {
if(pDev->device == PCI_DPT_DEVICE_ID ||
pDev->device == PCI_DPT_RAPTOR_DEVICE_ID){
if(adpt_install_hba(sht, pDev) ){
PERROR("Could not Init an I2O RAID device\n");
PERROR("Will not try to detect others.\n");
return hba_count-1;
}
pci_dev_get(pDev);
}
}
if (pDev)
pci_dev_put(pDev);


I don't see the point of the suggested place for the pci_dev_put()
since pci_dev_get() has never been executed in this case, or do I miss
anything?
