Subject: [PATCH] cpufreq: schedutil: Simplify sugov_fast_switch()
Date: Tue, 06 Oct 2020 14:01:31 +0200 [thread overview]
Message-ID: <1869109.WhRmcVd4D2@kreacher> (raw)
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Drop a redundant local variable definition from sugov_fast_switch()
and rearrange the code in there to avoid the redundant logical
negation.
Signed-off-by: Rafael J. Wysocki <rafael.j.wysocki@intel.com>

The code reads a bit easier after this change IMV.
linux-next material.
