[patch] iommu/vt-d: silence an uninitialized variable warning

My static checker complains that "dma_alias" is uninitialized unless we are dealing with a pci device. This is true but harmless. Anyway, we can flip the condition around to silence the warning. Signed-off-by: Dan Carpenter diff --git a/drivers/iommu/intel-iommu.c

[PATCH V2 4/5] iommu/msm: use generic ARMV7S short descriptor pagetable ops

This iommu uses the armv7 short descriptor format. So use the generic ARMV7S pagetable ops instead of rewriting the same stuff in the driver. Signed-off-by: Sricharan R --- drivers/iommu/Kconfig | 1 + drivers/iommu/msm_iommu.c | 378

[PATCH V2 2/5] iommu/msm: Move the contents from msm_iommu_dev.c to msm_iommu.c

[PATCH V2 0/5] iommu/msm: Add DT adaptation and generic bindings support

The msm_iommu.c driver currently works based on platform data. A single master device can be connected to more than one iommu and multiple contexts in each of the iommu. This association between master and iommus was represented from platform data using parent/child devices. The master drivers

[PATCH V2 5/5] iommu/msm: Remove driver BROKEN
