Subject: [Nouveau] [PATCH 08/15] drm/radeon: cleanup: drm_modeset_lock_all() --> DRM_MODESET_LOCK_ALL_BEGIN()
Date: Thu, 16 Sep 2021 23:15:45 +0200	[thread overview]
Message-ID: <20210916211552.33490-9-greenfoo@u92.eu> (raw)
In-Reply-To: <20210916211552.33490-1-greenfoo@u92.eu>

As requested in Documentation/gpu/todo.rst, replace driver calls to
drm_modeset_lock_all() with DRM_MODESET_LOCK_ALL_BEGIN() and
DRM_MODESET_LOCK_ALL_END()
