[PATCH] cpufreq: Drop unnecessary check from cpufreq_policy_alloc()

From: Rafael J. Wysocki
Date: Tue Aug 30 2016 - 21:06:37 EST


From: Rafael J. Wysocki <rafael.j.wysocki@xxxxxxxxx>

Since cpufreq_policy_alloc() doesn't use its dev variable for
anything useful, drop that variable from there along with the
NULL check against it.
