<content type='text'>
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.

<title>media: Kconfig: cleanup VIDEO_DEV dependencies</title>

<id>urn:sha1:9958d30f38b96fb763a10d44d18ddad39127d5f4</id>
<content type='text'>
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) &amp;&amp; VIDEO_DEV
		select RATIONAL
		select VIDEOBUF2_V4L2 if VIDEOBUF2_CORE
		default (I2C || I2C=n) &amp;&amp; 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.

This is the only tuner driver that has "tuner-" on its name.

Rename it, in order to match all the other tuner drivers.

<content type='text'>
The VIDIOC_G_FBUF and related overlay ioctls no longer worked (-ENOTTY was
returned).

The root cause was the introduction of the caps field in ivtv-driver.h.
While loading the ivtvfb module would update the video_device device_caps
field with V4L2_CAP_VIDEO_OUTPUT_OVERLAY it would not update that caps
field, and that's what the overlay ioctls would look at.

It's a bad idea to keep information in two places, so drop the caps field
and only use vdev.device_caps.

<content type='text'>
In [1], Christoph Hellwig has proposed to remove the wrappers in
include/linux/pci-dma-compat.h.

Some reasons why this API should be removed have been given by Julia
Lawall in [2].

A coccinelle script has been used to perform the needed transformation.
It can be found in [3].

Static variables do not need to be initialised to 0, because compiler
will initialise all uninitialised statics to 0. Thus, remove the
unneeded initializations.

The macro p_to_snd_ivtv_card() is just a variant for container_of(),
not actually used inside the code. So, drop it.

This address a clang warning.

This driver takes "osd_xres" and "osd_yres" as module parameters and
caps the upper bounds but it doesn't cap the lower bounds.  Obviously
the admin is not going to enter negative resolutions but the possibility
makes static analysis more difficult.
