  "message": "[PATCH] msi: sanely support hardware level msi disabling\n\nIn some cases when we are not using msi we need a way to ensure that the\nhardware does not have an msi capability enabled.  Currently the code has been\ncalling disable_msi_mode to try and achieve that.  However disable_msi_mode\nhas several other side effects and is only available when msi support is\ncompiled in so it isn\u0027t really appropriate.\n\nInstead this patch implements pci_msi_off which disables all msi and msix\ncapabilities unconditionally with no additional side effects.\n\npci_disable_device was redundantly clearing the bus master enable flag and\nclearing the msi enable bit.  A device that is not allowed to perform bus\nmastering operations cannot generate intx or msi interrupt messages as those\nare essentially a special case of dma, and require bus mastering.  So the call\nin pci_disable_device to disable msi capabilities was redundant.\n\nquirk_pcie_pxh also called disable_msi_mode and is updated to use pci_msi_off.\n\nSigned-off-by: Eric W.
