xtensa: Provide dummy dma_alloc_attrs() and dma_free_attrs()
xtensa:allmodconfig fails to build with the following errors. drivers/gpu/drm/nouveau/nvkm/subdev/instmem/gk20a.c: In function ‘gk20a_instobj_dtor_dma’: drivers/gpu/drm/nouveau/nvkm/subdev/instmem/gk20a.c:154:2: error: implicit declaration of function ‘dma_free_attrs’ drivers/gpu/drm/nouveau/nvkm/subdev/instmem/gk20a.c: In function ‘gk20a_instobj_ctor_dma’: drivers/gpu/drm/nouveau/nvkm/subdev/instmem/gk20a.c:218:2: error: implicit declaration of function ‘dma_alloc_attrs’ Xtensa does not provide those functions at this time. Provide dummy implementations to avoid build errors. Acked-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Guenter Roeck <linux@roeck-us.net> Signed-off-by: Chris Zankel <chris@zankel.net>
