Subject: [PATCH] drm/i915: Shrink cnl_ddi_buf_trans
Mime-version: 1.0
Content-type: text/plain; charset=UTF-8
Content-transfer-encoding: 8bit
Git-commit: fb5f4e96fdf9cb7ec5e6a590e1c3fdc3b6fd1e01
Patch-mainline: v4.15-rc1
References: FATE#322643 bsc#1055900

All the values we put into the CNL buf_trans tables fit into 8 bits.
So switch over to u8 from the u32 we use currently.
