Subject[PATCH 4.9 09/87] PM / OPP: Error out on failing to add static OPPs for v1 bindings
Date
4.9-stable review patch.  If anyone has any objections, please let me know.

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

From: Viresh Kumar <viresh.kumar@linaro.org>


[ Upstream commit 04a86a84c42ca18f37ab446127dc619b41dd3b23 ]

The code adding static OPPs for V2 bindings already does so. Make the V1
bindings specific code behave the same.
