drm/gma500: use ARRAY_SIZE
Using the ARRAY_SIZE macro improves the readability of the code. Also, it is useless to re-invent it. Found with Coccinelle with the following semantic patch: @r depends on (org || report)@ type T; T[] E; position p; @@ ( (sizeof(E)@p /sizeof(*E)) | (sizeof(E)@p /sizeof(E[...])) | (sizeof(E)@p /sizeof(T)) ) Reviewed-by: Thierry Reding <treding@nvidia.com> Signed-off-by: Jérémy Lefaure <jeremy.lefaure@lse.epita.fr> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: https://patchwork.freedesktop.org/patch/msgid/20171016023047.19145-1-jeremy.lefaure@lse.epita.fr
