Subject: [PATCH v2 2/2] PM / devfreq: exynos-bus: Disable devfreq-event device when fails
Date: Sun, 22 Dec 2019 17:41:32 +0000 [thread overview]
Message-ID: <20191222174132.3701-2-tiny.windzz@gmail.com> (raw)
In-Reply-To: <20191222174132.3701-1-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.
