Subject: [PATCH v4 04/20] drm: cleanup: drm_modeset_lock_all() --> DRM_MODESET_LOCK_ALL_BEGIN()
Date: Wed, 13 Oct 2021 22:48:30 +0200 [thread overview]
Message-ID: <20211013204846.90026-5-greenfoo@u92.eu> (raw)
In-Reply-To: <20211013204846.90026-1-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()
