Subject: [PATCH] drm/i915: Use fixed_16_16 wrapper for division operation
Git-commit: d273ecce3dde63168ed7840e2b8e5659da0df0f5
Patch-mainline: v4.13-rc1
References: FATE#322643 bsc#1055900
Don't use fixed_16_16 structure members directly, instead use wrapper to
perform fixed_16_16 division operation.
