Subject[PATCH 5.10 047/563] drm/rockchip: dsi: Fix unbalanced clock on probe error
Date
From: Brian Norris <briannorris@chromium.org>

[ Upstream commit 251888398753924059f3bb247a44153a2853137f ]

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")
