[PATCH 2/2] lib: scatterlist: Fix incorrect SG offset in sg_split_phys()

sg_split_phys() incorrectly resets the offset of all split SGLs but the first one to 0. This is wrong because one of the original SGLs might have the offset != 0. Signed-off-by: Alexander Egorenkov --- lib/sg_split.c | 2 -- 1 file changed, 2 deletions(-) diff --git a/lib/sg_split.c b/lib

[PATCH 1/1] lib: scatterlist: Fix SGL length in sg_split() if !CONFIG_NEED_SG_DMA_LENGTH
