Subject: drm/i915/skl: Move all the WM compute functions in one place
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=407b50f31ba19317cdc30530d30220182e42fa3d;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

drm/i915/skl: Move all the WM compute functions in one place

The DDB allocation code managed to split in two the compute functions.

Bring back skl_compute_transition_wm() and skl_compute_linetime_wm()
with their little friends.
