Subject: [PATCH] drm/ttm: soften TTM warnings
Date: Wed,  3 Mar 2021 16:57:57 +0100	[thread overview]
Message-ID: <20210303155757.82497-1-christian.koenig@amd.com> (raw)

QXL indeed unrefs pinned BOs and the warnings are spamming peoples log files.

Make sure we warn only once until the QXL driver is fixed.
