Subject: [PATCH 3/8] intel_idle: Clean up NULL pointer check in intel_idle_init()
Date: Fri, 10 Jan 2020 11:45:49 +0100 [thread overview]
Message-ID: <3687000.7TDbEkBDjF@kreacher> (raw)
In-Reply-To: <14127826.m9lEolTOYu@kreacher>
From: Rafael J. Wysocki <rafael.j.wysocki@intel.com>
Instead of comparing intel_idle_cpuidle_devices with NULL apply
the "!" (not) operator to it when checking it against NULL.
No intentional functional impact.
