Subject[PATCH 4.9 161/172] cpufreq: s3c2416: double free on driver init error path
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Dan Carpenter <dan.carpenter@oracle.com>

commit a69261e4470d680185a15f748d9cdafb37c57a33 upstream.

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)
