When attaching a PCI device manually via the comedi driver `attach` hook (`dio200_attach()`) (called by the comedi core for the `COMEDI_DEVCONFIG` ioctl), its reference count is incremented in the `for_each_pci_dev` loop (in `dio200_find_pci_dev()`). It is decremented when the `detach` hook (`dio200_detach()`) is called to detach the device. However, when the PCI device is attached automatically via the `attach_pci` hook (`dio200_attach_pci()`, called at probe time via `comedi_pci_auto_config()`) it's reference count is not incremented so there will be an unmatched decrement when detaching the device. Increment the PCI device reference count in `dio200_attach_pci()` to correct the mismatch. Once support for manual configuration has been removed from this driver, the calls to `pci_dev_get()` and `pci_dev_put()` can be removed.
