From 141a9a9cae282675375ef4523ba839927418a116 Mon Sep 17 00:00:00 2001 From: Brian Norris Date: Tue, 28 Sep 2021 14:35:51 -0700 Subject: [PATCH] drm/rockchip: dsi: Fix unbalanced clock on probe error MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit [ 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") Signed-off-by: Brian Norris Reviewed-by: Chen-Yu Tsai Tested-by: Nícolas F. R. A.
