Fixes the following coccicheck:
drivers/gpu/drm/amd/amdgpu/amdgpu_ttm.c:2427:16-17: WARNING opportunity for
min()
min() macro is defined in include/linux/minmax.h. It avoids multiple
evaluations of the arguments when non-constant and performs strict
type-checking.

Please double check that we don't need min_t() here.
With that done this patch and the _write variant are Reviewed-by:
