Subject: [PATCH 6/6] pxa_camera: fix smatch warning
Date: Thu,  7 Feb 2019 10:13:38 +0100	[thread overview]
Message-ID: <20190207091338.55705-7-hverkuil-cisco@xs4all.nl> (raw)
In-Reply-To: <20190207091338.55705-1-hverkuil-cisco@xs4all.nl>

drivers/media/platform/pxa_camera.c:2400 pxa_camera_probe() error: we previously assumed 'pcdev->pdata' could be null (see line 2397)

First check if platform data is provided, then check if DT data is provided,
and if neither is provided just return with -ENODEV.
