While that didn't change anything for quiet sometime, it actually become important after CSC code rework with commit ea067aee45a8 ("drm/sun4i: de2/de3: Remove redundant CSC matrices"). Without this fix, colours are completely off for supported YVU formats on SoCs with DE2 (A64, H3, R40, etc.). Fix the issue by enclosing macro arguments in parenthesis.
