Hi all, the above three functions can only return errors if the bus code failed to allocate the dma_parms structure, which is a grave error that won't get us far. Thus remove the pointless return values, that so far have fortunately been mostly ignored, but which the cleanup brigade now wants to check for for no good reason. Changes since v1: - fix SCSI to not call dma_set_max_seg_size and dma_set_seg_boundary unconditionally Diffstat: drivers/accel/qaic/qaic_drv.c | 4 -- drivers/dma/idma64.c | 4 -- drivers/dma/pl330.c | 5 --- drivers/dma/qcom/bam_dma.c | 6 ---- drivers/dma/sh/rcar-dmac.c | 4 -- drivers/dma/ste_dma40.c | 6 ---- drivers/gpu/drm/mediatek/mtk_drm_drv.c | 6 ---- drivers/media/common/videobuf2/videobuf2-dma-contig.c | 3 -- drivers/media/pci/intel/ipu6/ipu6.c | 4 -- drivers/mmc/host/mmci_stm32_sdmmc.c | 3 +- drivers/net/ethernet/microsoft/mana/gdma_main.c | 6 ---- drivers/scsi/lpfc/lpfc_init.c | 7 ----- drivers/scsi/scsi_lib.c | 11 ++++++- include/linux/dma-mapping.h | 25 +++++++----------- 14 files changed, 32 insertions(+), 62 deletions(-)
