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 part are given below. 'xilly_pci_direction()' has been hand modified to simplify it slightly. It has been compile tested. @@ @@ - PCI_DMA_BIDIRECTIONAL + DMA_BIDIRECTIONAL @@ @@ - PCI_DMA_TODEVICE + DMA_TO_DEVICE @@ @@ - PCI_DMA_FROMDEVICE + DMA_FROM_DEVICE @@ expression e1, e2; @@ - pci_set_dma_mask(e1, e2) + dma_set_mask(&e1->dev, e2) [1]: https://lore.kernel.org/kernel-janitors/20200421081257.GA131897@infradead.org/ [2]: https://lore.kernel.org/kernel-janitors/alpine.DEB.2.22.394.2007120902170.2424@hadrien/ Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> --- drivers/char/xillybus/xillybus_pcie.c | 9 ++++----- 1 file changed, 4 insertions(+), 5 deletions(-)
