Subject: [PATCH v3 2/4] video / backlight: remove the backlight_device_registered API
Date: Wed, 27 Apr 2016 12:45:03 +0000 [thread overview]
Message-ID: <1461761105-5961-3-git-send-email-aaron.lu@intel.com> (raw)
In-Reply-To: <1461761105-5961-1-git-send-email-aaron.lu@intel.com>
Since we will need the backlight_device_get_by_type API, we can use it
instead of the backlight_device_registered API whenever necessary so
remove the backlight_device_registered API.
