Subject: [PATCH v2 5/6] drm/exynos: hdmi: convert to of_drm_find_and_get_bridge()
Date: Fri, 09 Jan 2026 11:02:54 +0100	[thread overview]
Message-ID: <20260109-drm-bridge-alloc-getput-drm_of_find_bridge-3-v2-5-8d7a3dbacdf4@bootlin.com> (raw)
In-Reply-To: <20260109-drm-bridge-alloc-getput-drm_of_find_bridge-3-v2-0-8d7a3dbacdf4@bootlin.com>

of_drm_find_bridge() is deprecated. Move to its replacement
of_drm_find_and_get_bridge() which gets a bridge reference, and ensure it
is put when done.
