Hello! I think there is a bug in pcie-iproc-msi.c driver. It declares Multi MSI support via MSI_FLAG_MULTI_PCI_MSI flag, see: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/pci/controller/pcie-iproc-msi.c?h=v5.12#n174 but its iproc_msi_irq_domain_alloc() function completely ignores nr_irqs argument when allocating interrupt numbers from bitmap, see: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/pci/controller/pcie-iproc-msi.c?h=v5.12#n246 I think this this is incorrect as alloc callback should allocate nr_irqs multi interrupts as caller requested. All other drivers with Multi MSI support are doing it. Could you look at it?
