drm/ttm: rename ttm_fbdev_mmap
Rename ttm_fbdev_mmap to ttm_bo_mmap_obj. Move the vm_pgoff sanity check to amdgpu_bo_fbdev_mmap (only ttm_fbdev_mmap user in tree). The ttm_bo_mmap_obj function can now be used to map any buffer object. This allows to implement &drm_gem_object_funcs.mmap in gem ttm helpers. v3: patch added to series Signed-off-by: Gerd Hoffmann <kraxel@redhat.com> Acked-by: Thomas Zimmermann <tzimmermann@suse.de> Reviewed-by: Christian König <christian.koenig@amd.com> Acked-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/20191016115203.20095-8-kraxel@redhat.com
