I usually need the struct video_device 'priv' field to obtain the main
structure using the new v4l1 interface (video_devdata() in particular). On
open , for example:
int open(struct file* filp, ..., ....)
{
...
struct my_device* camera =
(struct my_device*)video_devdata(filp)->priv;
...
}
I think it is more clear this way...
