Clang build with CONFIG_DRM_DEBUG_MM=n, CONFIG_WERROR=y, and W=1 leads
to:
CC [M] drivers/gpu/drm/drm_mm.o
../drivers/gpu/drm/drm_mm.c:614:20: error: function 'drm_mm_node_scanned_block'
is not needed and will not be emitted [-Werror,-Wunneeded-internal-declaration]
static inline bool drm_mm_node_scanned_block(const struct drm_mm_node *node)
^
Fix this by annotating drm_mm_node_scanned_block() with __maybe_unused.
