[PATCH v3 3/4] drm/rockchip: dsi: Fix unbalanced clock on probe error

From: Brian Norris
Date: Tue Sep 28 2021 - 17:36:18 EST


Our probe() function never enabled this clock, so we shouldn't disable
it if we fail to probe the bridge.

Noted by inspection.

Fixes: 2d4f7bdafd70 ("drm/rockchip: dsi: migrate to use dw-mipi-dsi bridge driver")
