drm: Kconfig: Let all DRM_GEM_CMA_HELPER related macros depend on HAVE_DMA_ATTRS
DRM_GEM_CMA_HELPER is depend on HAVE_DMA_ATTRS, or it will break the building. The related error (with allmodconfig under xtensa): CC [M] drivers/gpu/drm/drm_gem_cma_helper.o drivers/gpu/drm/drm_gem_cma_helper.c: In function 'drm_gem_cma_create': drivers/gpu/drm/drm_gem_cma_helper.c:110:19: error: implicit declaration of function 'dma_alloc_writecombine' [-Werror=implicit-function-declaration] cma_obj->vaddr = dma_alloc_writecombine(drm->dev, size, ^ drivers/gpu/drm/drm_gem_cma_helper.c:110:17: warning: assignment makes pointer from integer without a cast [-Wint-conversion] cma_obj->vaddr = dma_alloc_writecombine(drm->dev, size, ^ drivers/gpu/drm/drm_gem_cma_helper.c: In function 'drm_gem_cma_free_object': drivers/gpu/drm/drm_gem_cma_helper.c:193:3: error: implicit declaration of function 'dma_free_writecombine' [-Werror=implicit-function-declaration] dma_free_writecombine(gem_obj->dev->dev, cma_obj->base.size, ^ drivers/gpu/drm/drm_gem_cma_helper.c: In function 'drm_gem_cma_mmap_obj': drivers/gpu/drm/drm_gem_cma_helper.c:330:8: error: implicit declaration of function 'dma_mmap_writecombine' [-Werror=implicit-function-declaration] ret = dma_mmap_writecombine(cma_obj->base.dev->dev, vma, ^ Signed-off-by: Chen Gang <gang.chen.5i5j@gmail.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
