Subject: [PATCH] PM / devfreq: tegra30:  disable clock on error in probe
Date: Tue, 8 Sep 2020 10:25:57 +0300	[thread overview]
Message-ID: <20200908072557.GC294938@mwanda> (raw)

This error path needs to call clk_disable_unprepare().

Fixes: 7296443b900e ("PM / devfreq: tegra30: Handle possible round-rate error")
