complained for over 2 years, I take it that these parameters were no

The Kinect sensor is a device used by Microsoft for its Kinect project,
which is a system for controller-less Human-Computer interaction
targeted for Xbox 360.
In the Kinect device, RGBD data is captured from two distinct sensors: a
regular RGB sensor and a monochrome sensor which, with the aid of a IR
structured light, captures what is finally exposed as a depth map; so
what we have is basically a Structured-light 3D scanner.
The Kinect gspca subdriver just supports the video stream for now,
exposing the output from the RGB sensor or the unprocessed output from
the monochrome sensor; it does not deal with the processed depth stream
yet, but it allows using the sensor as a Webcam or as an IR camera (an
external source of IR light might be needed for this use).
The low level implementation is based on code from the OpenKinect
project (http://openkinect.org).

Thanks go to Jeff Campbell and Mike Bradley for reproting the problem, and

reset GPIO line, the demodulator I2C address, and that the GPIOs have to be
reinitialized after a cardtype switch.

The em28xx bridge strobes the reset pin on the drx-d on every ts_ctrl call.
This results in the state of the chip getting out of the sync with the
state of the driver (and hence all tuning requests after the first one fail).
Make sure the drx-d is not being held in reset, but don't actually perform a
hardware reset on the chip.
The GPIO block has been split out from the other HVR-9x0 variants to reduce
the risk of regression, although in theory they would not have any issues
since none of those cases have the frontend driver managing any internal
state.

If the tuner is not actually behind an i2c gate, using the i2c gate control
function can wedge the i2c bus. Provide the ability to control on a per-board
basis whether it should be used.
Problem was noticed on the HVR-900 R2, where it resulted in the first tuning
attempt succeeding, and then all subsequent attempts to access the xc3028
being treated as failures (including the call to sleep the tuner).

The v4l2_subdev_* functions are meant for older V4L2 drivers that do not use
the control framework yet. These functions should not be used by subdev_do_ioctl.
Most of those backwards compatibility functions are just stubs, but commit
87a0c94ce6 actually changed the behavior of
v4l2_subdev_queryctrl, so calling that one from subdev_do_ioctl broke the
control enumeration in subdev nodes.
The fix is simply not to use those compatibility functions in v4l2-subdev.c.

Some v4l drivers currently don't initialize their struct v4l2_subdev
with zeros, and this is a problem since some of the v4l2 code expects
this. One example is the addition of internal_ops in commit 45f6f84,
after that we are at risk of random oopses with these drivers when code
in v4l2_device_register_subdev tries to dereference sd->internal_ops->*,
as can be shown by the report at http://bugs.launchpad.net/bugs/745213
and analysis of its crash at https://lkml.org/lkml/2011/4/1/168
Use kzalloc within problematic drivers to ensure we have a zeroed struct
v4l2_subdev.
