4.9-stable review patch. If anyone has any objections, please let me know.
------------------
From: Chanwoo Choi <cw00.choi@xxxxxxxxxxx>
commit 32dd7731699765f21dbe6df9020e613d4ed73fc3 upstream.
This patch fixes the wrong return value. If devfreq driver requires the wrong
and non-available governor, it is fail. So, this patch returns the error
insead of -EPROBE_DEFER.
Fixes: 403e0689d2a9 (PM / devfreq: exynos: Add support of bus frequency of sub-blocks using passive governor)
