| Subject: drm/imx: imx-ldb: check if channel is enabled before printing warning |
| |
| From: Lucas Stach <l.stach@pengutronix.de> |
| |
| [ Upstream commit c80d673b91a6c81d765864e10f2b15110ee900ad ] |
| |
| If the second LVDS channel has been disabled in the DT when using dual-channel |
| mode we should not print a warning. |
