This patch looks good, but there was one other thing that caught my eye. In s2255_probe_v4l, video_device_alloc is called for each video device, which is nothing more than a call to kzalloc, but the result of the call is never verified.
Given that this driver has a fixed number of video device nodes, the array of video_device structs could be allocated within the s2255_dev struct. This would remove the extra calls to video_device_alloc, video_device_release, and the additional error checks that should have been there. If you'd prefer to keep the array of video_device structs independent of the s2255_dev struct, an alternative would be to dynamically allocate the entire array at once using kcalloc and store only the pointer to the array in the s2255_dev struct. In my opinion, either of these methods would be better than calling video_device_alloc for each video device that needs to be registered.
