[PATCH 2/3] cpufreq: dt: Print error on failing to mark OPPs as shared

From: Viresh Kumar
Date: Wed Sep 02 2015 - 05:07:22 EST


We need to explicitly mark OPPs as shared, when they are not defined
with OPP-v2 bindings. This operation can potentially fail, and in that
case we should at least print an error message.

Fixes: 2e02d8723edf ("cpufreq: dt: Add support for operating-points-v2 bindings")
