Subject: [PATCH 0/2] drm/imx: parallel-display: fix drm/panel/panel-simple
 v6.17 WARNING regression

This series fixes the WARNING regressions reported by Ernest [0] and due to
the missing conversion of the DRM_IMX driver to the new
devm_drm_bridge_alloc() API.

The second patch also adds drm_bridge_add(), which is a good practice and
proposed to become mandatory [1].
