Thomas Gleixner dd7f5a11ac PCI/MSI: Remove bogus warning in pci_irq_get_affinity() ... The recent overhaul of pci_irq_get_affinity() introduced a regression when pci_irq_get_affinity() is called for an MSI-X interrupt which was not allocated with affinity descriptor information. The original code just returned a NULL pointer in that case, but the rework added a WARN_ON() under the assumption that the corresponding WARN_ON() in the MSI case can be applied to MSI-X as well. In fact the MSI warning in the original code does not make sense either because it's legitimate to invoke pci_irq_get_affinity() for a MSI interrupt which was not allocated with affinity descriptor information. Remove it and just return NULL as the original code did.
