- * @dev:	The PCI device to operate on

- *		IMS instance (PASID, queue ID, pointer...).
- *		The cookie content is copied into the MSI descriptor for the
- *		interrupt chip callbacks or domain specific setup functions.
- * @affdesc:	Optional pointer to an interrupt affinity descriptor
- *
- * There is no index for IMS allocations as IMS is an implementation
- * specific storage and does not have any direct associations between
- * index, which might be a pure software construct, and device
- * functionality. This association is established by the driver either via
- * the index - if there is a hardware table - or in case of purely software
- * managed IMS implementation the association happens via the
- * irq_write_msi_msg() callback of the implementation specific interrupt
- * chip, which utilizes the provided @icookie to store the MSI message in
- * the appropriate place.
- *
- * Return: A struct msi_map
- *
- *	On success msi_map::index contains the allocated index (>= 0) and
- *	msi_map::virq the allocated Linux interrupt number (> 0).
- *
- *	On fail msi_map::index contains the error code and msi_map::virq
- *	is set to 0.
