Make this a proper typed array. Drop the old allocate context code since
that is no longer used.
Note that the memops functions now get a struct device pointer instead of
the struct device ** that was there initially (actually a void pointer to
a struct containing only a struct device pointer).
This code is now a lot cleaner.

Changeset 7b9f31f3b3ca ("[media] sta2x11_vip: fix s_std") removed
autodetect code, but it kept two vars unused:
drivers/media/pci/sta2x11/sta2x11_vip.c: In function 'vidioc_s_std':
drivers/media/pci/sta2x11/sta2x11_vip.c:448:6: warning: unused variable 'status' [-Wunused-variable]

drivers/media/pci/sta2x11/sta2x11_vip.c:447:14: warning: unused variable 'oldstd' [-Wunused-variable]
v4l2_std_id oldstd = vip->std;
^
Remove them.

The s_std ioctl was broken in this driver, partially due to the
changes to the adv7180 driver (this affected the handling of
V4L2_STD_ALL) and partially because the new standard was never
stored in vip->std.
The handling of V4L2_STD_ALL has been rewritten to just call querystd
and the new standard is now stored correctly.

The queue_setup callback has a void pointer that is just for V4L2
and is the pointer to the v4l2_format struct that was passed to
VIDIOC_CREATE_BUFS. The idea was that drivers would use the information
from that struct to buffers suitable for the requested format.
After the vb2 split series this pointer is now a void pointer,
which is ugly, and the reality is that all existing drivers will
effectively just look at the sizeimage field of v4l2_format.
To make this more generic the queue_setup callback is changed:
the void pointer is dropped, instead if the *num_planes argument
is 0, then use the current format size, if it is non-zero, then
it contains the number of requested planes and the sizes array
contains the requested sizes. If either is unsupported, then return
-EINVAL, otherwise use the requested size(s).

Remove v4l2 stuff - v4l2_buf, v4l2_plane - from struct vb2_buffer.
Add new member variables - bytesused, length, offset, userptr, fd,
data_offset - to struct vb2_plane in order to cover all information
of v4l2_plane.
struct vb2_plane {
<snip>
unsigned int bytesused;
unsigned int length;
union {
unsigned int offset;
unsigned long userptr;
int fd;
} m;
unsigned int data_offset;
}
Replace v4l2_buf with new member variables - index, type, memory - which
are common fields for buffer management.
struct vb2_buffer {
<snip>
unsigned int index;
unsigned int type;
unsigned int memory;
unsigned int num_planes;
struct vb2_plane planes[VIDEO_MAX_PLANES];
<snip>
};
v4l2 specific fields - flags, field, timestamp, timecode,
sequence - are moved to vb2_v4l2_buffer in videobuf2-v4l2.c
struct vb2_v4l2_buffer {
struct vb2_buffer vb2_buf;
__u32 flags;
__u32 field;
struct timeval timestamp;
struct v4l2_timecode timecode;
__u32 sequence;

Add media controller support to the adv7180 driver by registering a media
entity instance for it as well as implementing pad ops for configuring the
format.
As there currently don't seem to be any users of the video ops format
operations those are removed as well in this patch.
Also set the V4L2_SUBDEV_FL_HAS_DEVNODE flag for the subdevice so it is
possible to create a subdevice device node.
Since the driver now depends on VIDEO_V4L2_SUBDEV_API all drivers which
select the driver need to depend on that symbol as well.

The v4l2_pix_format structure has no reserved field. It is embedded in
the v4l2_framebuffer structure which has no reserved fields either, and
in the v4l2_format structure which has reserved fields that were not
previously required to be zeroed out by applications.
To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer
structure, and use the priv field as a magic value to indicate that the
application has set all v4l2_pix_format extended fields and zeroed all
reserved fields following the v4l2_pix_format field in the v4l2_format
structure.
The availability of this API extension is reported to userspace through
the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the
priv field is still set to the magic value at [GS]_FMT return wouldn't
be enough, as older kernels don't zero the priv field on return.
To simplify the internal API towards drivers zero the extended fields
and set the priv field to the magic value for applications not aware of
the extensions.

The vb2 core ignores any return code from the stop_streaming op.
And there really isn't anything it can do anyway in case of an error.
So change the return type to void and update any drivers that implement it.
The int return gave drivers the idea that this operation could actually
fail, but that's really not the case.
The pwc amd sdr-msi3101 drivers both had this construction:
if (mutex_lock_interruptible(&s->v4l2_lock))
return -ERESTARTSYS;
This has been updated to just call mutex_lock(). The stop_streaming op
expects this to really stop streaming and I very much doubt this will
work reliably if stop_streaming just returns without really stopping the
DMA.

If a queue was canceled, then the buf_finish op was never called for the
pending buffers. So add this call to queue_cancel. Before calling buf_finish
set the buffer state to PREPARED, which is the correct state. That way the
states DONE and ERROR will only be seen in buf_finish if streaming is in
progress.
Since buf_finish can now be called from non-streaming state we need to
adapt the handful of drivers that actually need to know this.

The buf_finish op should always work, so change the return type to void.
Update the few drivers that use it.

The orig code will release all the resources if v4l2_device_register()
failed and return 0. But what we need in this case is to return an
negative error code to let the caller known we are failed.
So the patch save the return value of v4l2_device_register() to 'ret'
and return it when error.

This is due to the lack of I2C support:
...
> CONFIG_I2C is not set
...
So, Make sure that sta2x11_vip depends on I2C.

This ioctl is defined as IOW, so pass the argument by value instead of by
reference. I could have chosen to add const instead, but this is 1) easier
to handle in drivers and 2) consistent with the s_std subdev operation.

This patch re-write the driver and use the videobuf2
interface instead of the old videobuf. Moreover, it uses also
the control framework which allows the driver to inherit
controls from its subdevice (ADV7180). Finally the driver does not
implement custom file operation but it uses the generic ones from
videobuf2 and v4l2_fh

CONFIG_HOTPLUG is going away as an option. As a result, the __dev*
markings need to be removed.
This change removes the use of __devinit, __devexit_p, __devinitdata,
__devinitconst, and __devexit from these drivers.
Based on patches originally written by Bill Pemberton, but redone by me
in order to handle some of the coding style issues better, by hand.

Instead of having 3 options to allow customizing the media
sub-drivers (tuners, I2C drivers, frontends), merge all of
them into just one.
That simplifies the life for users, as they can just keep
this untouched.
Life for developers is also simpler, as there's now just
one Kconfig item to remember, for the ancillary sub-drivers
providing supports for chips that could change from one
board design to another.
