PCI/MSI: Correct 'can_mask' test in msi_add_msi_desc()
71020a3c0dff4 ("PCI/MSI: Use msi_add_msi_desc()") inadvertently reversed
the sense of "msi_attrib.can_mask" in one use:
- if (entry->pci.msi_attrib.can_mask) {
- addr = pci_msix_desc_addr(entry);
- entry->pci.msix_ctrl = readl(addr + PCI_MSIX_ENTRY_VECTOR_CTRL);
+ if (!desc.pci.msi_attrib.can_mask) {
+ addr = pci_msix_desc_addr(&desc);
+ desc.pci.msix_ctrl = readl(addr + PCI_MSIX_ENTRY_VECTOR_CTRL);
Restore the original test.
