Subject: [PATCH 2/2] PM / devfreq: exynos-bus: add missing exynos_bus_disable_edev in exynos_bus_profile_init
Date: Sat, 21 Dec 2019 18:18:55 +0000	[thread overview]
Message-ID: <20191221181855.31380-2-tiny.windzz@gmail.com> (raw)
In-Reply-To: <20191221181855.31380-1-tiny.windzz@gmail.com>

The exynos_bus_profile_init process may fail, but the devfreq event device
remains enabled. Call devfreq_event_disable_edev on the error return path.
