Subject: [PATCH v4 8/8] media: staging/imx: Don't set driver data for v4l2_dev
Date: Fri, 3 May 2019 15:43:26 -0700 [thread overview]
Message-ID: <20190503224326.21039-9-slongerbeam@gmail.com> (raw)
In-Reply-To: <20190503224326.21039-1-slongerbeam@gmail.com>
The media device is already available via multiple methods, there is no
need to set driver data for v4l2_dev to the media device.
In imx_media_link_notify(), get media device from link->graph_obj.mdev.
In imx_media_capture_device_register(), get media device from
v4l2_dev->mdev.
