Subject: [PATCH] drm: silence variable 'conn' set but not used
Git-commit: bbb6fc43f131f77fcb7ae8081f6d7c51396a2120
Patch-mainline: v5.3-rc2
References: bsc#1051510

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.
