All fbdev clients now run these calls. For non-PCI devices or drivers without vga-switcheroo, this does nothing. For i915 and radeon, it allows these drivers to use a common fbdev client. The device is the same as the one stored in struct drm_client and struct drm_fb_helper, so there is no difference in behavior. Some NULL-pointer checks are being removed, where those pointers cannot be NULL. v4: - clarify call semantics for drm_fb_helper_unregister_info() (Javier) Signed-off-by: Thomas Zimmermann Reviewed-by: Javier Martinez Canillas --- drivers/gpu/drm/drm_fb_helper.c | 17 ++++++++++++----- 1 file changed, 12 insertions(+), 5 deletions(-) diff --git a/drivers/gpu/drm/drm_fb_helper.c b/drivers/gpu/drm/drm_fb_helper.c index af1fe79c701d..550fa69311cb 100644 --- a/drivers/gpu/drm/drm_fb_helper.c +++ b/drivers/gpu/drm/drm_fb_helper.c @@ -554,7 +554,7 @@ EXPORT_SYMBOL(drm_fb_helper_release_info); /** * drm_fb_helper_unregister_info - unregister fb_info framebuffer device - * @fb_helper: driver-allocated fbdev helper, can be NULL + * @fb_helper: driver-allocated fbdev helper, must not be NULL * * A wrapper around unregister_framebuffer, to release the fb_info * framebuffer device.
