Subject: drm/i915: Use alphabetical names for sprites
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Add sprite_name() macro which should be used with the kind of sprites
that are fixed to pipes (gen4.5+).

Also use dev_priv->num_plane to calculate the sprite index insted
assuming two sprites per pipe. This should make it print the right
name.
