Subject: [PATCH v4 5/5] devfreq: exynos-bus: remove
 exynos_bus_passive_target()

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Both functions exynos_bus_passive_target() and exynos_bus_target()
have the same code, so remove exynos_bus_passive_target(). In
exynos_bus_probe() replace it with exynos_bus_target.
