Subject: [PATCH v4 14/36] hrtimer: Use accesor functions instead of direct access
Date: Thu, 21 Dec 2017 11:41:43 +0100	[thread overview]
Message-ID: <20171221104205.7269-15-anna-maria@linutronix.de> (raw)
In-Reply-To: <20171221104205.7269-1-anna-maria@linutronix.de>

__hrtimer_hres_active() is now available unconditionally. Replace the
direct access to hrtimer_cpu_base.hres_active.

No functional change.
