Dependency of CONFIG_INTEL_IOMMU_FLOPPY_WA on CONFIG_BLK_DEV_FD was
added in kernel commit cb3db5a39e2a6b6396df1780d39a250f649d2e3a
("iommu/vt-d: Set INTEL_IOMMU_FLOPPY_WA depend on BLK_DEV_FD").
Fix the following warning:
[NOTE]: 'CONFIG_INTEL_IOMMU_FLOPPY_WA' last val (y) and .config val (n) do
not match
[INFO]: CONFIG_INTEL_IOMMU_FLOPPY_WA : n
[INFO]: raw config text:
config INTEL_IOMMU_FLOPPY_WA
bool
default y
depends on X86 && BLK_DEV_FD && INTEL_IOMMU && IOMMU_SUPPORT
help
Floppy disk drivers are known to bypass DMA API calls
thereby failing to work when IOMMU is enabled. This
workaround will setup a 1:1 mapping for the first
16MiB to make floppy (an ISA device) work.
Config 'INTEL_IOMMU_FLOPPY_WA' has the following Direct dependencies
(INTEL_IOMMU_FLOPPY_WA=n):
X86(=y) && BLK_DEV_FD(=n) && INTEL_IOMMU(=y) &&
IOMMU_SUPPORT(=y)
Parent dependencies are:
BLK_DEV_FD [n] IOMMU_SUPPORT [y] X86 [y] INTEL_IOMMU [y]
[INFO]: config 'CONFIG_INTEL_IOMMU_FLOPPY_WA' was set, but it wasn't
assignable, check (parent) dependencies
