Subject: [PATCH V5 09/10] PM / OPP: Don't WARN on multiple calls to dev_pm_opp_set_regulators()
Date: Tue, 29 Nov 2016 12:06:56 +0530	[thread overview]
Message-ID: <2b7f54b32e1a07d8dbfcdbccf1c71aa8657f32f8.1480401041.git.viresh.kumar@linaro.org> (raw)
In-Reply-To: <cover.1480401041.git.viresh.kumar@linaro.org>
In-Reply-To: <cover.1480401041.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.
