- * pci_resize_resource - reconfigure a Resizable BAR and resources
- * @dev: the PCI device
- * @resno: index of the BAR to be resized
- * @size: new size as defined in the spec (0=1MB, 31=128TB)
- * @exclude_bars: a mask of BARs that should not be released
- *
- * Reconfigure @resno to @size and re-run resource assignment algorithm
- * with the new size.
- *
- * Prior to resize, release @dev resources that share a bridge window with
- * @resno.  This unpins the bridge window resource to allow changing it.
- *
- * The caller may prevent releasing a particular BAR by providing
- * @exclude_bars mask, but this may result in the resize operation failing
- * due to insufficient space.
- *
- * Return: 0 on success, or negative on error. In case of an error, the
- *         resources are restored to their original places.
