Subject: [PATCH v2 3/3] drm/panel: lg-sw43408: use devm_drm_panel_add()
Date: Thu, 23 Apr 2026 21:59:22 +0900	[thread overview]
Message-ID: <20260423125922.57428-4-mhun512@gmail.com> (raw)
In-Reply-To: <20260423125922.57428-1-mhun512@gmail.com>

Replace drm_panel_add()/drm_panel_remove() with devm_drm_panel_add()
now that drm-misc-next provides it. This keeps panel deregistration tied
to the device lifetime and removes the manual cleanup from the remove
callback.
