Subject: [PATCH 1/2] cpufreq: ppc-corenet: remove duplicate update of cpu_data
Date: Tue,  2 Sep 2014 09:11:24 +0530	[thread overview]
Message-ID: <09092df3d8b03df99ee475357c5f5c9cc439c61c.1409629117.git.viresh.kumar@linaro.org> (raw)

'cpu_data' is updated for policy->cpu first and then for all CPUs in
policy->cpus. policy->cpus is guaranteed to contain policy->cpu as well and so
the first write to 'cpu_data' for policy->cpu is redundant. Remove it.

Hi Yuantian,

I was looking into this driver due to issues reported by Hongtao (cc'd) and
found that we can live without some code. These aren't fixing any bugs and are
just cleanups.

I didn't had a compiler for this and so this isn't even compiled. It would be
great if you can please review/test these patches.
