Subject: [PATCH 1/2] cpufreq: drivers: don't check range of target freq in .target()
Date: Sun, 24 Mar 2013 20:59:42 +0530	[thread overview]
Message-ID: <2ece6d9fe8dfb6882a1c83a1cb2404bacc40b22d.1364138740.git.viresh.kumar@linaro.org> (raw)

Cpufreq core checks the range of target_freq before calling driver->target() and
so we don't need to do it again.

Remove it.
