From 639fd77e2f696269b3a5c7a1eb547e044e4dbc2b Mon Sep 17 00:00:00 2001 From: Christophe JAILLET Date: Sat, 18 Sep 2021 07:32:26 +0200 Subject: tifm: Remove usage of the deprecated "pci-dma-compat.h" API 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]. Finally, Arnd Bergmann reminded that the documentation was updated 11 years ago to only describe the modern linux/dma-mapping.h interfaces and mark the old bus-specific ones as no longer recommended, see commit 216bf58f4092 ("Documentation: convert PCI-DMA-mapping.txt to use the generic DMA API"). A coccinelle script has been used to perform the needed transformation Only relevant parts are given below. @@ expression e1, e2, e3, e4; @@ - pci_map_sg(e1, e2, e3, e4) + dma_map_sg(&e1->dev, e2, e3, e4) @@ expression e1, e2, e3, e4; @@ - pci_unmap_sg(e1, e2, e3, e4) + dma_unmap_sg(&e1->dev, e2, e3, e4) @@ 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/ Reviewed-by: Arnd Bergmann Signed-off-by: Christophe JAILLET Link: https://lore.kernel.org/r/b5296677f92f7bace957e66479b3d57a5a824ca1.1631942796.git.christophe.jaillet@wanadoo.fr Signed-off-by: Greg Kroah-Hartman --- drivers/misc/tifm_core.c | 5 +++-- 1 file changed, 3 insertions(+), 2 deletions(-) (limited to 'drivers/misc/tifm_core.c') diff --git a/drivers/misc/tifm_core.c b/drivers/misc/tifm_core.c index 2bb46b1f4be3..a3098fea3bf7 100644 --- a/drivers/misc/tifm_core.c +++ b/drivers/misc/tifm_core.c @@ -292,14 +292,15 @@ EXPORT_SYMBOL(tifm_has_ms_pif); int tifm_map_sg(struct tifm_dev *sock, struct scatterlist *sg, int nents, int direction) { - return pci_map_sg(to_pci_dev(sock->dev.parent), sg, nents, direction); + return dma_map_sg(&to_pci_dev(sock->dev.parent)->dev, sg, nents, + direction); } EXPORT_SYMBOL(tifm_map_sg); void tifm_unmap_sg(struct tifm_dev *sock, struct scatterlist *sg, int nents, int direction) { - pci_unmap_sg(to_pci_dev(sock->dev.parent), sg, nents, direction); + dma_unmap_sg(&to_pci_dev(sock->dev.parent)->dev, sg, nents, direction); } EXPORT_SYMBOL(tifm_unmap_sg); -- cgit v1.2.3-59-g8ed1b
