Subject: [PATCH V2 8/8] PM / OPP: Don't WARN on multiple calls to dev_pm_opp_set_regulators()
Date: Thu, 20 Oct 2016 14:15:02 +0530 [thread overview]
Message-ID: <3017eefdae58adc192ccb9c829fa32ee9b58c799.1476952750.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1476952750.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1476952750.git.viresh.kumar@linaro.org>
If a platform specific OPP driver has called this routine first and set
the regulators, then the second call from cpufreq-dt driver will hit the
WARN_ON(). Remove the WARN_ON(), but continue to return error in such
cases.
