+Subject: soc/tegra: pmc: Fix imbalanced clock disabling in error code path
+
+From: Dmitry Osipenko <digetx@gmail.com>
+
+commit 19221e3083020bd9537624caa0ee0145ed92ba36 upstream.
+
+The tegra_powergate_power_up() has a typo in the error code path where it
+will try to disable clocks twice, fix it. In practice that error never
+happens, so this is a minor correction.
