In [1], Christoph Hellwig has proposed to remove the wrappers in include/linux/pci-dma-compat.h. Some reasons why this API should be removed have been given by Julia Lawall in [2]. A coccinelle script has been used to perform the needed transformation Only relevant parts are given below. @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ expression e1, e2, e3, e4; @@ - pci_map_single(e1, e2, e3, e4) + dma_map_single(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_single(e1, e2, e3, e4) + dma_unmap_single(&e1->dev, e2, e3, e4) [1]: https://lore.kernel.org/kernel-janitors/20200421081257.GA131897@xxxxxxxxxxxxx/ [2]: https://lore.kernel.org/kernel-janitors/alpine.DEB.2.22.394.2007120902170.2424@hadrien/ Signed-off-by: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> --- arch/powerpc/include/asm/floppy.h | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) diff --git a/arch/powerpc/include/asm/floppy.h b/arch/powerpc/include/asm/floppy.h index 7af9a68fd949..f8ce178b43b7 100644 --- a/arch/powerpc/include/asm/floppy.h +++ b/arch/powerpc/include/asm/floppy.h @@ -134,17 +134,19 @@ static int hard_dma_setup(char *addr, unsigned long size, int mode, int io) int dir; doing_vdma = 0; - dir = (mode == DMA_MODE_READ) ?
