Subject: [PATCH v3 1/4] devfreq: exynos-bus: Extract exynos_bus_profile_init()
Date: Mon, 9 Dec 2019 11:48:59 +0100 [thread overview]
Message-ID: <20191209104902.11904-2-a.swigon@samsung.com> (raw)
In-Reply-To: <20191209104902.11904-1-a.swigon@samsung.com>
This patch adds a new static function, exynos_bus_profile_init(), extracted
from exynos_bus_probe().
