From: Maarten Lankhorst Date: Wed, 9 Mar 2016 09:35:44 +0000 (+0100) Subject: drm/i915: Remove some post-commit members from intel_crtc->atomic, v3. X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=cd202f69d89c48a935d4763ff96c50e762ed2e0a;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git drm/i915: Remove some post-commit members from intel_crtc->atomic, v3. fb_bits is useful to have in the crtc_state for cs flips when the code is updated to use intel_frontbuffer_flip_prepare/complete. So calculate it in advance and move it to crtc_state. The other stuff can be calculated in post_plane_update, and aren't useful elsewhere. Changes since v1: - Changing wording, remove comment about loop. Changes since v2: - Rebase.
