Subject: [PATCH v6 4/4] drm/bridge: lvds-codec: simplify error handling
Date: Fri, 26 Jun 2020 12:01:03 +0200 [thread overview]
Message-ID: <20200626100103.18879-5-a.hajda@samsung.com> (raw)
In-Reply-To: <20200626100103.18879-1-a.hajda@samsung.com>
Using dev_err_probe code has following advantages:
- shorter code,
- recorded defer probe reason for debugging,
- uniform error code logging.
