From: Qian Cai <cai@xxxxxx> [ Upstream commit bbb6fc43f131f77fcb7ae8081f6d7c51396a2120 ] The "struct drm_connector" iteration cursor from "for_each_new_connector_in_state" is never used in atomic_remove_fb() which generates a compilation warning, drivers/gpu/drm/drm_framebuffer.c: In function 'atomic_remove_fb': drivers/gpu/drm/drm_framebuffer.c:838:24: warning: variable 'conn' set but not used [-Wunused-but-set-variable] Silence it by marking "conn" __maybe_unused.
