Hidetoshi Seto 0d07348931 PCI MSI: Return if alloc_msi_entry for MSI-X failed ... In current code it continues setup even if alloc_msi_entry() for MSI-X is failed due to lack of memory. It means arch_setup_msi_irqs() might be called with msi_desc entries less than its argument nvec. At least x86's arch_setup_msi_irqs() uses list_for_each_entry() for dev->msi_list that suspected to have entries same numbers as nvec, and it doesn't check the number of allocated vectors and passed arg nvec. Therefore it will result in success of pci_enable_msix(), with less vectors allocated than requested. This patch fixes the error route to return -ENOMEM, instead of continuing the setup (proposed by Matthew Wilcox). Note that there is no iounmap in msi_free_irqs() if no msi_disc is allocated.
