Subject: [patch] cpufreq: s3c2416: double free on driver init error path
Date: Tue, 7 Feb 2017 16:19:06 +0300 [thread overview]
Message-ID: <20170207131906.GD27416@mwanda> (raw)
The "goto err_armclk;" error path already does a clk_put(s3c_freq->hclk);
so this is a double free.
Fixes: 34ee55075265 ("[CPUFREQ] Add S3C2416/S3C2450 cpufreq driver")
