Pull MSI fixes from Marc Zyngier: "Thomas tasked me with sending out a few urgent fixes after the giant MSI rework that landed in 6.2, as both s390 and powerpc ended-up suffering from it (they do not use the full core code infrastructure, leading to these previously undetected issues): - Return MSI_XA_DOMAIN_SIZE as the maximum MSI index when the architecture does not make use of irq domains instead of returning 0, which is pretty limiting. - Check for the presence of an irq domain when validating the MSI iterator, as s390/powerpc won't have one. - Fix powerpc's MSI backends which fail to clear the descriptor's IRQ field on teardown, leading to a splat and leaked descriptors" * tag 'msi-fixes-6.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/maz/arm-platforms: powerpc/msi: Fix deassociation of MSI descriptors genirq/msi: Return MSI_XA_DOMAIN_SIZE as the maximum MSI index when no domain is present genirq/msi: Check for the presence of an irq domain when validating msi_ctrl
