The Kconfig option that enables compiling camera sensor drivers is
VIDEO_CAMERA_SENSOR rather than MEDIA_CAMERA_SUPPORT as it was previously.
Fix this.
Also select VIDEO_OV7670 for marvell platform drivers only if
MEDIA_SUBDRV_AUTOSELECT and VIDEO_CAMERA_SENSOR are enabled.

Set the v4l2_device already in async notifier init, so struct device
related to it will be available before the notifier is registered. This
requires separating notifier initialisation into two functions, one that
takes v4l2_device as its argument, v4l2_async_nf_init and
v4l2_async_subdev_nf_init, for sub-device notifiers. Registering the
notifier will use a single function, v4l2_async_nf_register.
This is done in order to make struct device available earlier, during
construction of the async connections, for sensible debug prints.

Register V4L2 device before the async notifier. This way the device can be
made available to the V4L2 async framework from the notifier init time
onwards. A subsequent patch will add struct v4l2_device as an argument to
v4l2_async_nf_init().

Rename v4l2_async_subdev as v4l2_async_connection, in order to
differentiate between the sub-devices and their connections: one
sub-device can have many connections but the V4L2 async framework has so
far allowed just a single one. Connections in this context will later
translate into either MC ancillary or data links.
This patch prepares changing that relation by changing existing users of
v4l2_async_subdev to switch to v4l2_async_connection. Async sub-devices
themselves will not be needed anymore
Additionally, __v4l2_async_nf_add_subdev() has been renamed
__v4l2_async_nf_add_connection().

The driver can match only via the DT table so the table should be always
used and the of_match_ptr does not have any sense (this also allows ACPI
matching via PRP0001, even though it might not be relevant here). This
also fixes !CONFIG_OF error:

Commit 0d346d2a6f54 ("media: v4l2-subdev: add subdev-wide state struct")
applied a large media tree-wide change produced by coccinelle. It was so
large that a set of identical indentation issues went unnoticed during
review. Fix them.
While at it, and because it's easy to review both changes together, add
a trailing comma for the last (and only) struct member initialization of
the related structures, to avoid future changes should new fields need
to be initialized.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is (mostly) ignored
and this typically results in resource leaks. To improve here there is a
quest to make the remove callback return void. In the first step of this
quest all drivers are converted to .remove_new() which already returns
void.
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Fold mmpcam_remove() into its only caller mmpcam_platform_remove(). Note
that cam can never be zero, as the probe function calls
platform_set_drvdata() with a non-NULL argument (or returns an error
code in which case .remove() won't be called).
Also use mmpcam_remove() as the function name for the remove callback to
align to mmpcam_probe() for .probe().

The bus_info field is set by most drivers based on the type of the device
bus as well as the name of the device. Do this in v4l_querycap() so
drivers don't need to. This keeps compatibility with non-default and silly
bus_info.

media Kconfig has two entries associated to V4L API:
VIDEO_DEV and VIDEO_V4L2.
On Kernel 2.6.x, there were two V4L APIs, each one with its own flag.
VIDEO_DEV were meant to:
1) enable Video4Linux and make its Kconfig options to appear;
2) it makes the Kernel build the V4L core.
while VIDEO_V4L2 where used to distinguish between drivers that
implement the newer API and drivers that implemented the former one.
With time, such meaning changed, specially after the removal of
all V4L version 1 drivers.
At the current implementation, VIDEO_DEV only does (1): it enables
the media options related to V4L, that now has:
menu "Video4Linux options"
visible if VIDEO_DEV
source "drivers/media/v4l2-core/Kconfig"
endmenu
but it doesn't affect anymore the V4L core drivers.
The rationale is that the V4L2 core has a "soft" dependency
at the I2C bus, and now requires to select a number of other
Kconfig options:
config VIDEO_V4L2
tristate
depends on (I2C || I2C=n) && VIDEO_DEV
select RATIONAL
select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
default (I2C || I2C=n) && VIDEO_DEV
In the past, merging them would be tricky, but it seems that it is now
possible to merge those symbols, in order to simplify V4L dependencies.
Let's keep VIDEO_DEV, as this one is used on some make *defconfig
configurations.
