Subject: [PATCH 4.9 111/130] PM / devfreq: exynos-bus: Fix the wrong return value

4.9-stable review patch.  If anyone has any objections, please let me know.

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

From: Chanwoo Choi <cw00.choi@...sung.com>

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)
