The 'from' variable at preview_config() expects an __user * type.

However, the logic there does:

    from = *(void * __user *) ((void *)cfg + attr->config_offset);

With actually means a void pointer, pointing to a void __ user
pointer. When the first pointer is de-referenced with *(foo),
the type it returns is "void *" instead of "void __user *".

Change it to:
    from = *(void __user **) ((void *)cfg + attr->config_offset);

in order to obtain, when de-referenced, a void __user pointer,
as desired.

That prevent those warnings:

if v4l2_subdev_call(..., VENC_GET_FLD,...) fails, it
currently returns a random value. Instead, return 1.

That's probably better than returning 0, as this is very
likely what happens in practice with the current code, as
as the probably of an unititialized 32 bits integer to
have an specific value (0, in this case), is 1/(2^32).

An alternative would be to return an error code, and
let the caller to hint, based on the past received
frame, but that sounds weird.

As warned:
	drivers/staging/media/davinci_vpfe/dm365_ipipe.c:1834 vpfe_ipipe_init() error: we previously assumed 'res' could be null (see line 1797)

There's something wrong at vpfe_ipipe_init():

1) it caches the resourse_size() from from the first region
   and reuses to the second region;

2) the "res" var is overridden 3 times;

3) at free logic, it assumes that "res->start" is not
   overridden by platform_get_resource(pdev, IORESOURCE_MEM, 6),
   but that's not true, as it can even be NULL there.

This patch fixes the above issues by:

a) store the resources used by release_mem_region() on
   a separate var;

b) stop caching resource_size(), using the function where
   needed.

The dm365_ipipe_hw.c and dm365_ipipe.c file check if several table
pointers, declared at davinci_vpfe_user.h, are filled before using
them.

The problem is that those pointers come from struct declarations
like:

	struct vpfe_ipipe_yee {
	...
	short table[VPFE_IPIPE_MAX_SIZE_YEE_LUT];
	};

So, they can't be NULL! Solve those warnings:
