The first part of this work can be found here: https://lore.kernel.org/r/20211126222700.862407977@linutronix.de This second part has the following important changes: 1) Cleanup of the MSI related data in struct device struct device contains at the moment various MSI related parts. Some of them (the irq domain pointer) cannot be moved out, but the rest can be allocated on first use. This is in preparation of adding more per device MSI data later on. 2) Consolidation of sysfs handling As a first step this moves the sysfs pointer from struct msi_desc into the new per device MSI data structure where it belongs. Later changes will cleanup this code further, but that's not possible at this point. 3) Store per device properties in the per device MSI data to avoid looking up MSI descriptors and analysing their data. Cleanup all related use cases. 4) Provide a function to retrieve the Linux interrupt number for a given MSI index similar to pci_irq_vector() and cleanup all open coded variants.
