drm/gem: rename struct drm_gem_dma_object.{paddr => dma_addr}
The field paddr of struct drm_gem_dma_object holds a DMA address, which might actually be a physical address. However, depending on the platform, it can also be a bus address or a virtual address managed by an IOMMU. Hence, rename the field to dma_addr, which is more applicable. In order to do this renaming the following coccinelle script was used: ``` @@ struct drm_gem_dma_object *gem; @@ - gem->paddr + gem->dma_addr @@ struct drm_gem_dma_object gem; @@ - gem.paddr + gem.dma_addr @exists@ typedef dma_addr_t; symbol paddr; @@ dma_addr_t paddr; <... - paddr + dma_addr ...> @@ symbol paddr; @@ dma_addr_t - paddr + dma_addr ; ``` This patch is compile-time tested with: ``` make ARCH={x86_64,arm,arm64} allyesconfig make ARCH={x86_64,arm,arm64} drivers/gpu/drm` ``` Acked-by: Sam Ravnborg <sam@ravnborg.org> Suggested-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Danilo Krummrich <dakr@redhat.com> Signed-off-by: Sam Ravnborg <sam@ravnborg.org> Link: https://patchwork.freedesktop.org/patch/msgid/20220802000405.949236-5-dakr@redhat.com
