Subject: [PATCH v5 4/9] media: staging/imx: Move add_video_device into capture_device_register
Date: Fri, 10 May 2019 14:50:07 -0700 [thread overview]
Message-ID: <20190510215012.13881-5-slongerbeam@gmail.com> (raw)
In-Reply-To: <20190510215012.13881-1-slongerbeam@gmail.com>
Move imx_media_add_video_device() into imx_media_capture_device_register().
Also the former has no error conditions to convert to void.
