After using the new VIDIOC_DBG_G_CHIP_NAME ioctl I realized that the matching
by name possibility is useless. Just drop it and rename MATCH_SUBDEV_IDX to
just MATCH_SUBDEV.
The v4l2-dbg utility is much better placed to match by name by just enumerating
all bridge and subdev devices until chip_name.name matches.Signed-off-by: Hans Verkuil

Only enable this ioctl if the VIDEO_ADV_DEBUG config option is set. This
prevents abuse from both userspace and kernelspace (some bridge drivers
abuse DBG_G_CHIP_IDENT, lets prevent that from happening again with this
ioctl).Signed-off-by: Hans Verkuil

The struct v4l2_capability card field stores the device name. That name
can be hardcoded in drivers, or be retrieved directly from the device.
The later is very common with USB devices. As several devices already
report names that include non-ASCII characters, update the field
description to use UTF-8.Signed-off-by: Laurent Pinchart

This patch adds a helper function that allows to modify range,
i.e. minimum, maximum, step and default value of a v4l2 control,
after the control has been created and initialized. This is helpful
in situations when range of a control depends on user configurable
parameters, e.g. camera sensor absolute exposure time depending on
an output image resolution and frame rate.
v4l2_ctrl_modify_range() function allows to modify range of an
INTEGER, BOOL, MENU, INTEGER_MENU and BITMASK type controls.

The DVBv3 statistics parameters are limited on several ways:
- It doesn't provide any way to indicate the used measure,
so userspace need to guess how to calculate/use it;
- Only a limited set of stats are supported;
- Can't be called in a way to require them to be filled
all at once (atomic reads from the hardware), with may
cause troubles on interpreting them on userspace;
- On some OFDM delivery systems, the carriers can be
independently modulated, having different properties.
Currently, there's no way to report per-layer stats.
To address the above issues, adding a new DVBv5-based stats API.
While here, correct inner code nomenclature on a few places.Reviewed-by: Antti Palosaari

__devinitconst, and __devexit from the kernel documentation.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.Cc: Bill Pemberton
