For VIDIOC_QUERYBUF only the first two fields, size and type, are used as
input. The rest can be filled in by the driver as output. Most drivers do
not actually use all the field and unused ones should be zeroed out. Some
drivers have code to do this and some drivers should but don't. So put
some zero out code in v4l2_ioctl so that all drivers using that system get
it.
The drivers that have zeroing code get that code removed.
Some drivers checked that the type field was valid, but v4l2_ioctl already
does this so those checks can be removed as well.

The zoran i2c modules were still using V4L1 internally. Replace this
with V4L2. Also deleted saa7111.c and saa7114.c, we use saa7115.c instead.

The zoran driver does a module_get/put of THIS_MODULE on device open/close.
This isn't necessary as the kernel does this automatically.
Clean up the failure path of zoran_open() somewhat.
Make the dprintk()s on open/close a higher debug level and make the user
count printed take the current open/close into account.

The driver should only use the kernel mapped io address, zr36057_mem, and
not the PCI bus address, zr36057_adr. Since the latter is only printed out
once, there is no need to save it in the driver data structure.
There was some old code that looked like it was for the Alpha architecture
which would use the PCI bus address. It probably no longer applies to
modern kernels.

Instead of using custom code, just let the device layer look it up for us
from the pci device table. This requires extending the pci device table to
list each known card, plus a catch-all entry for the cards that don't have
sub-system vendor/device data.
Improve some of the info and error messages too.

The driver was keeping a global array with an entry for each zoran device
probed. It was a leftover from when the driver didn't dynamically allocate
the driver data for each device.
There was only one use left, in the video device's ->open() method, looking
up the struct zoran for the opened device from the minor number. This can
be done better with video_get_drvdata().
Since zoran_num is now only used in the pci driver's ->probe() method, it
doesn't need to be an atomic_t and be static. There is a race if multiple
zoran cards could be probed at the same time, but currently the probe
method for a given driver is single threaded.

When initializing a module parameter that is a per-card array, use
"{ [0 ... (BUZ_MAX-1)] = -1 }" instead of "{ -1, -1, -1, -1 }". This way
all of the entries will be correctly set to -1 if someone changes BUZ_MAX
to a value other than 4.
Adjust some of the parameter help text too.

Changeset 60b4bde48b36c0315ef41fd38c339b9c7e68c46f removed an unused
struct on zoran driver, when compiled with "Y".
However, as pointed by Jean Delvare <khali@linux-fr.org>, this is
neeeded when the driver is compiled as a module, since udev relies on it
to auto-load the module.

Since internal to v4l2 the ioctl prototype is the same regardless of it
being called through .ioctl or .unlocked_ioctl, we need to convert it all
to the long return type of unlocked_ioctl.
Thanks to Jean-Francois Moine for posting an initial patch for this and
thus bringing it to our attention.

Introduce a struct v4l2_file_operations for v4l2 drivers.
Remove the unnecessary inode argument.
Move compat32 handling (and llseek) into the v4l2-dev core: this is now
handled in the v4l2 core and no longer in the drivers themselves.
Note that this changeset reverts an earlier patch that changed the return
type of__video_ioctl2 from int to long. This change will be reinstated
later in a much improved version.

The inode argument was never used. Removing it from video_usercopy
brings the function pointer type of video_usercopy in line with similar
v4l2 functions, thus simplifying several drivers.
