From 0cdc1d07b4616f164978e8f1b3a5fe8b0a3ac835 Mon Sep 17 00:00:00 2001 From: Maarten Lankhorst Date: Tue, 8 Jan 2019 17:08:41 +0100 Subject: [PATCH] drm/i915: Make HW readout mark CRTC scaler as in use. This way we don't accidentally double allocate it. Noticed this when I wrote a patch to sanity check all of the scaler state.
