When building with W=1, the following warning occurs.
drivers/gpu/drm/radeon/radeon_ttm.c:200:20: warning: variable ‘rbo’ set but not
used [-Wunused-but-set-variable]
struct radeon_bo *rbo;
The variable 'rbo' is used only in WARN_ON_ONCE in the function
radeon_bo_move, and WARN_ON_ONCE is removed in the following
patch, so we removed 'rbo' to remove the
-Wunused-but-set-variable warning.
Fixes: f87c1f0b7b79 ("drm/ttm: prevent moving of pinned BOs")
