This patch allows configuring a board to use either one way.

There were some vestiges of an old V4L1 I2C driver that were called by em28xx.
This patch removes this dead code, and replaces videodev.h to videodev2.h

Now, this driver doesn't require V4L1 anymore.

Uses the newer ioctl handler at videodev. This patch also cleans up some
bad logic at the driver and do CodingStyle and other cleanups at the
resulting driver.

Also, since VIDIOCMBUF were not working, the V4L1 compat code were removed.
The compat code will eventually be re-inserted, if we find a clean way for
implementing compatibility with the old API.

set video standards, etc.

This patch were splited from Markus Rechberger's tree and backported to 2.6.17

Adds autodetection support for the Cinergy200 USB and the VGear PocketTV.

gets scanned for connected i2c devices. If the device list matches an em2800

The attached patch modifies the em28xx driver so that there can be ioctls from
multiple different threads.

This is necessary for capture apps like MPlayer that use different threads for
capturing and channel tuning.

Now the locking is only done for the ioctls that change properties of the
device or access the i2c bus.

It also removes some locks that look unnecessary:

In em28xx_init_dev:
  the videodevice is not registered yet so nothing can access the hardware
 meanwhile, the device struct is not assigned to the interface yet so no race
 with disconnect is possible

In em28xx_release_resources:
  it gets only called when dev->lock is already held

Currently, the only tuner-specific device that allows special
configurations is tda9887. However, tea5767 also may require some
special configurations (for example, to specify a different Xtal freq).

This patch replaces TDA9887_SET_CONFIG by a more generic internal ioctl
(TUNER_SET_CONFIG). The newer one allows specifying what tuner is
appliable to a configuration set, and allows an arbitrary configuration
struct.

This em28xx-video.c uses functions from this header, but doesn't include it.
It depends on some v4l headers included two levels down including poll.h,
which includes mm.h.

These v4l headers might change, so it's best to include the headers needed
directly.

It also causes problems for the out of core build system's backward
compatibility with older kernels, which is the real reason I bothered to
create a patch for something that would otherwise be so minor that it would
hardly be worth the trouble.

struct video_device used to define a .hardware field. While
initialized on severl drivers, this field is never used inside V4L.
However, drivers using it need to include the old V4L1 header.

This seems to cause compilation troubles with some random configs.
Better just to remove it from all drivers.

There is one list_for_each+list_entry in cpia_pp.c that
wasn't changed because it expects the loop iterator to remain NULL if
the list is empty.

If, in em28xx_usb_probe() the memory allocation
	dev->alt_max_pkt_size = kmalloc(32*
						dev->num_alt,GFP_KERNEL);
fails, then we'll bail out and return -ENOMEM.
The problem is that in that case we don't free the storage allocated
to 'dev', thus causing a memory leak.

This patch fixes the leak by freeing 'dev' before we return -ENOMEM.

Many struct file_operations in the kernel can be "const".  Marking them const
moves these to the .rodata section, which avoids false sharing with potential
dirty data.  In addition it'll catch accidental writes at compile time to
these shared resources.
