Subject: [PATCH 6/9] drm/bridge: use drm_for_each_bridge_in_chain_scoped()
Date: Wed, 23 Jul 2025 11:54:13 +0200 [thread overview]
Message-ID: <20250723-drm-bridge-alloc-getput-for_each_bridge-v1-6-be8f4ae006e9@bootlin.com> (raw)
In-Reply-To: <20250723-drm-bridge-alloc-getput-for_each_bridge-v1-0-be8f4ae006e9@bootlin.com>
Use drm_for_each_bridge_in_chain_scoped() instead of
drm_for_each_bridge_in_chain() to ensure the bridge being looped on is
refcounted.
