Subject: [PATCH 16/19] clocksource: mips-gic: Use percpu_dev_id
Date: Mon, 20 Oct 2014 12:04:03 -0700 [thread overview]
Message-ID: <1413831846-32100-17-git-send-email-abrestic@chromium.org> (raw)
In-Reply-To: <1413831846-32100-1-git-send-email-abrestic@chromium.org>
Since the GIC timer IRQ is a percpu IRQ, we can use percpu_dev_id
to pass the IRQ handler the correct clock_event_device.
