iommu\/dma-iommu: Fix wrong scatterlist length assignment in P2PDMA path<\/p>\n
In iommu_dma_map_sg(), when handling PCI P2PDMA cases, the DMA length
\nof the current scatterlist segment `s` is incorrectly assigned from the
\nhead entry `sg->length` instead of the current entry `s->length`.<\/p>\n
This typo causes all P2PDMA segments in the scatterlist to inherit the
\nlength of the first segment, leading to corrupted DMA lengths for multi-
\nsegment scatterlists.<\/p>\n
Fix this by using `s->length` instead of `sg->length`.<\/p>\n","protected":false},"excerpt":{"rendered":"
