Subject: [Nouveau] [PATCH 02/15] dmr/i915: cleanup: drm_modeset_lock_all_ctx() --> DRM_MODESET_LOCK_ALL_BEGIN()
Date: Thu, 16 Sep 2021 23:15:39 +0200	[thread overview]
Message-ID: <20210916211552.33490-3-greenfoo@u92.eu> (raw)
In-Reply-To: <20210916211552.33490-1-greenfoo@u92.eu>

As requested in Documentation/gpu/todo.rst, replace the boilerplate code
surrounding drm_modeset_lock_all_ctx() with DRM_MODESET_LOCK_ALL_BEGIN()
and DRM_MODESET_LOCK_ALL_END()
