Subject: [PATCH 1/7] cpufreq: intel_pstate: Remove duplicate CPU ID check
Date: Tue, 10 Jun 2014 00:00:09 +0300	[thread overview]
Message-ID: <53962059.6070306@semaphore.gr> (raw)

We check the CPU ID during driver init. There is no need
to do it again per logical CPU initialization.

So, remove the duplicate check.
