This updates the cx88-blackbird driver to be able to use the new cx23416
firmware image released by Hauppauge Computer Works, while retaining
compatibility with the older firmware images.
cx2341x firmware can be downloaded at: http://dl.ivtvdriver.org/ivtv/firmware/

Due to changes in the i2c handling in 2.6.20 this cx25840 bug surfaced,
causing the firmware load to fail for the ivtv driver. The correct
sequence is to first attach the i2c client, then use the client's
device to load the firmware.

An I2C adapter needs to register an association with the actual parent
device. Until 2.6.20, not doing this was a benign problem; now it
causes an ugly warning in the system log. This 1-line patch corrects
that oversight.

The pvrusb2 driver previously rejected encoder firmware whose size was
not a multiple of 8192. But this is a false check because it's
possible to find cx23416 firmware whose size doesn't conform to this
limit. So change the firmware loader implementation to be more
forgiving of the image size.

From: Hans Verkuil <hverkuil@xs4all.nl>
Due to changes in the /sys directory structure a bug in the cx25840 firmware
load surfaced in 2.6.20: the device passed to request_firmware was wrong:
instead of the i2c device the i2c adapter was passed. Because of this an
attemp was made to create a kobject with the adapter name inside the
adapter directory, but a kobject with that name already exists.
Now pass the i2c device itself so that the correct /sys directory is used.
This way the firmware can be loaded again.

Follows the same coding style for commented code
The latest patch series added a different way of commenting unused patches:
#ifdef notdef
But V4L/DVB coding style uses, instead:
#if 0
This have also the advantage of not sending to mainstream those development codes
that doesn't make sense at a production environment, while keeping them under
development trees.

The out of tree v4l-dvb build system didn't always override the kernel's
configuration settings with v4l-dvb's settings correctly. To work around
this, makefiles would define some new macro based on the setting of a
config variable. e.g. the pwc Makefile would define CONFIG_PWC_DEBUG if
CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set.
The v4l-dvb build system should now always override correctly, and this
is no longer necessary. This patch gets ride of these extra defines and
just uses the CONFIG_* settings directly.

input_register_device() was changed to return an error code instead of
being void in 2.6.15. Handle it with a macro wrapper in config.h. For
this to work, linux/input.h must be included before config.h. This
required some trivial header re-ordering in budget-ci.c and ttusb_dec.c.
In kernel 2.6.15-rc1 a helper function called setup_timer() was added to
linux/timer.h. Add to compat.h, but require that linux/timer.h be
included first to give the definition of struct timer_list.
A new 4GB DMA zone, __GFP_DMA32, was added in 2.6.15-rc2. Alias it to
__GFP_DMA on older kernels.
Handle another 2.6.15 "input_dev->dev to input_dev->cdev.dev" change for
some recently added code in cinergyT2.c.

Before, root privileges were only needed to set hardware registers, not
to read them. On some hardware, reading from the wrong place at the
wrong time can hang the machine. So, to be consistent, root privileges
are required to read registers on all hardware.

Support 64 bit register IDs internally. Only allow root access to
this API (for both set and get). Note that actual 64 bit access only
becomes possible once the definition for v4l2_register is updated, but
this change clears the way for it from the viewpoint of the pvrusb2
driver.

Several special-case FX2 commands were being issued through
pvr2_write_u16() and pvr2_write_8(), but there's really nothing
special case about them. These date from a very early time in the
driver development. This patch removes these functions and replaces
their use with calls to pvr2_send_request.

Functions buffer_release() in bttv-driver.c and
vbi_buffer_release() in bttv-vbi.c are ending with:
bttv_dma_free(&fh->cap,fh->btv,buf);
For vbi it seems to be wrong. Both functions should end with:
bttv_dma_free(q,fh->btv,buf);

From: Mauro Carvalho Chehab <mchehab@infradead.org>
Before this patch, vivi were simulating a scatter gather DMA transfer.
While this is academic, showing how stuff really works on a real PCI
device, this means a non-optimized code.
There are only two memory models that vivi implements:
1) kernel alloced memory. This is also used by read() method.
On this case, a vmalloc32 buffer is allocated at kernel;
2) userspace allocated memory. This is used by most userspace apps.
video-buf will store this pointer.
a simple copy_to_user is enough to transfer data.
The third memory model scenario supported by video-buf is overlay mode.
This model is not implemented on vivi and unlikely to be implemented on
newer drivers, since now, most userspace apps do some post-processing
(like de-interlacing).
After this patch, some cleanups may be done at video-buf.c to avoid
allocating pages, when the driver doesn't need a PCI buffer. This is the
case of vivi and usb drivers.

The direct register access ioctls were defined as kernel internal only,
but they are very useful for debugging hardware from userspace and are
used as such. Officially export them.
VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER
Definition of ioctl and struct v4l2_register is moved from v4l2-common.h
to videodev2.h.
Types used in struct v4l2_register are changed to the userspace
exportable versions (u32 -> __u32, etc).
Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move
the check into the video_ioctl2() dispatcher so it doesn't need to be
duplicated in each driver's call-back function.
CAP_SYS_ADMIN check is added to pvrusb2 (which doesn't use video_ioctl2).
