Subject: [PATCH v2 4/8] drm/rockchip: dw_dp: Simplify error handling
Date: Tue, 10 Mar 2026 00:44:32 +0200 [thread overview]
Message-ID: <20260310-drm-rk-fixes-v2-4-645ecfb43f49@collabora.com> (raw)
In-Reply-To: <20260310-drm-rk-fixes-v2-0-645ecfb43f49@collabora.com>
Make the code a bit more compact by getting rid of the superfluous
assignments around PTR_ERR().
While at it, also drop dev assignment in dw_dp_probe().
