From f7e5838bb37d970e103b1d9af3928f0f471c8a48 Mon Sep 17 00:00:00 2001 From: Chris Wilson Date: Wed, 13 Apr 2016 17:35:07 +0100 Subject: [PATCH] drm/i915: Simplify reset_counter handling during atomic modesetting Now that the reset_counter is stored on the request, we can rearrange the code to handle reading the counter versus waiting during the atomic modesetting for readibility (by deleting the hairiest of codes).
