Subject: [PATCH 4/5] drm/i915: Make HW readout mark CRTC scaler as in use.
Date: Mon, 17 Dec 2018 10:50:23 +0100	[thread overview]
Message-ID: <20181217095024.2340-4-maarten.lankhorst@linux.intel.com> (raw)
In-Reply-To: <20181217095024.2340-1-maarten.lankhorst@linux.intel.com>

This way we don't accidentally double allocate it and hopefully disable
it during fastset. I noticed this when I wrote a patch to sanity check
all of the scaler state.
