Is it just cleanup? Hi Stuart, it's not just cleanup, because "[RFC PATCH 08/11] PCI/MSI: Introduce new struct msi_irqs and struct msi_ops" introduced struct msi_irqs, so the code will change to if (!dev->msi_irqs->msi_enabled) I think driver should not need to know the details of MSI members. So I try to rework the pci_dev_msi_enabled() to hide the detailed MSI info. Thanks! Yijing. > > . > -- Thanks!
