| Subject: drm: silence variable 'conn' set but not used |
| |
| [ 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. |
