usb_control_msg initiates (and waits for completion of) a dma transfer using
the supplied buffer. That buffer thus has to be seperately allocated on
the heap.
In lib/dma_debug.c the function check_for_stack even warns about it:
WARNING: at lib/dma-debug.c:866 check_for_stack
Note: This change is tested to compile only, as I don't have the hardware.

In commit 8aff8ba95155df, most of the manipulations to vbuf inside
copy_streams were gated on if !dev->radio, but one place that touches
vbuf lays outside those gates -- a memcpy of vbuf isn't NULL. If we
initialize vbuf to NULL, that memcpy will never happen in the case where
we do have dev->radio, and otherwise, in the !dev->radio case, the code
behaves exactly like it did prior to 8aff8ba95155df.
While we're at it, also fix an incorrectly indented closing brace for
one of the sections touching vbuf that is conditional on !dev->radio.

Thanks to some excellent investigative work by Douglas Clowes, it was
uncovered that the older w83667hg Nuvoton chip functions with this
driver after actually enabling the CIR function via its multi-function
chip config register. The CIR and CIR wide-band sensor enable bits are
just in a different place on this hardware, so we only poke register
0x27 on 677 hardware now, and we poke register 0x2c on the 667 now.

There are additional chip IDs that report a PNP ID of NTN0530, which we
were refusing to load on. Instead, lets just warn if we encounter an
unknown chip, as there's a chance it will work just fine.
Also, expand the list of known hardware to include both an earlier and a
later generation chip that this driver should function with. Douglas has
an older w83667hg variant, that with a touch more work, will be
supported by this driver, and Lutz has a newer w83677hg variant that
works without any further modifications to the driver.

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).

tuners
A previous changes which added the newer model HVR-1600's and DTV support for
them, neglected to add RF analog TV for them. Fix RF analog TV for the newer
HVR-1600's which have a worldwide analog tuner assembly with a TDA18271 tuner
and TDA8295 demodulator.
Thanks go to Jeff Campbell and Mike Bradley for reproting the problem, and
also to Mike Bradley for doing a lot of the legwork to figure out the tuner
reset GPIO line, the demodulator I2C address, and that the GPIOs have to be
reinitialized after a cardtype switch.

The macro is defined as:
#define CHK_ERROR(s) if( (status = s)<0 ) break
This sucks, as makes harder to debug if something got wrong and
there are more than one level of loops. Also, violates CodingStyle.
Fixed by this simple perl script:
while (<>) { $f.=$_; };
$f=~ s,\n\#define CHK_ERROR[^\n]+\n,\n,;
$f=~ s=(CHK_ERROR\(.*\,)\n\s+=\1 =g;
$f=~ s=(CHK_ERROR\(.*\,)\n\s+=\1 =g;
$f=~ s=(CHK_ERROR\(.*\,)\n\s+=\1 =g;
$f=~ s=(CHK_ERROR\(.*)\s+(\,)\n\s+=\1\2 =g;
$f=~ s=(CHK_ERROR\(.*)\s+(\,)\n\s+=\1\2 =g;
$f=~ s=(CHK_ERROR\(.*)\s+(\,)\n\s+=\1\2 =g;
$f=~ s,\n(\t+)CHK_ERROR\((.*)\)\;,\n\1status = \2;\n\1if (status < 0)\n\1\tbreak;,g;
print $f;
Plus a few manual adjustments

This file is big. It has 12000+ lines! Most of the defined stuff aren't
used anyware inside the driver, so we can just remove most of the lines
and still keep everything that have any interest for the driver.
If anyone ever need the other devices, it will be stored at git logs, so
it is easy to recover.
The diff result is impressive:
1 files changed, 1013 insertions(+), 12694 deletions(-)
rewrite drivers/media/dvb/frontends/drxd_map_firm.h (90%)
As a sideback effect, drxd driver will likely compile faster, and
checkpatch.pl can run on this file without taking (literally) hours.
The code cleanup was done using this small script:
$ for i in `perl -ne 'print "$1\n" if (m/define\s+([^\s+]+)/)' drxd_map_firm.h`; do if [ "`grep $i drivers/media/dvb/frontends/drxd*.[ch]`" != "" ] ; then echo $i; fi; done|sort|uniq >used_symbols
$ grep -f used_symbols drxd_map_firm.h >defines
And then deleting the old #define lines, replacing by "defines" file content.
