Pci_dev_msi_enabled() is used to check whether device MSI/MSIX enabled. Refactor this function to suuport checking only device MSI or MSIX enabled. Signed-off-by: Yijing Wang <wangyijing at huawei.com> --- arch/cris/arch-v32/drivers/pci/bios.c | 2 +- arch/frv/mb93090-mb00/pci-vdk.c | 2 +-...

An Intel MIC X100 device is a PCIe form factor add-in coprocessor card based on the Intel Many Integrated Core (MIC) architecture that runs a Linux OS. It is a PCIe endpoint in a platform and therefore implements the three required standard address spaces i.e. configuration, memory and I/O. The host OS loads a device driver as is typical for PCIe devices. The card itself runs a bootstrap after
