From: Ville Syrjälä Date: Thu, 2 Mar 2017 17:14:54 +0000 (+0200) Subject: drm/i915: Plop vlv wm state into crtc_state X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=855c79f5212acced123c1a6be3c12601f45e8da9;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Plop vlv wm state into crtc_state Relocate the vlv/chv wm state to live under intel_crtc_state. Note that for now this just behaves as a temporary storage. But it'll be easier to conver the thing over to properly pre-computing the state when it's already in the right place.
