[PATCH v6 4/4] drm/bridge: lvds-codec: simplify error handling

From: Andrzej Hajda <hidden>
Date: 2020-06-26 10:01:23
Also in: dri-devel, lkml
Subsystem: drm drivers, drm drivers and misc gpu patches, drm drivers for bridge chips, the rest · Maintainers: David Airlie, Simona Vetter, Maarten Lankhorst, Maxime Ripard, Thomas Zimmermann, Andrzej Hajda, Neil Armstrong, Robert Foss, Linus Torvalds

Using dev_err_probe code has following advantages:
- shorter code,
- recorded defer probe reason for debugging,
- uniform error code logging.
