drm/fb-helper: add DRM_FB_HELPER_DEFAULT_OPS for fb_ops
The define DRM_FB_HELPER_DEFAULT_OPS provides the drm_fb_helper default implementations for functions in struct fb_ops. A drm driver can use it like: static struct fb_ops drm_fbdev_cma_ops = { .owner = THIS_MODULE, DRM_FB_HELPER_DEFAULT_OPS, /* driver specific implementations */ }; Suggested-by: Daniel Vetter <daniel@ffwll.ch> Signed-off-by: Stefan Christ <contact@stefanchrist.eu> Reviewed-by: Gustavo Padovan <gustavo.padovan@collabora.co.uk> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1475182136-15191-2-git-send-email-contact@stefanchrist.eu
