[Mike Isely: This is the pvrusb2 affected part of a much larger patch
in the kernel from Tejun Heo]
sysfs is now completely out of driver/module lifetime game. After
deletion, a sysfs node doesn't access anything outside sysfs proper,
so there's no reason to hold onto the attribute owners. Note that
often the wrong modules were accounted for as owners leading to
accessing removed modules.
This patch kills now unnecessary attribute->owner. Note that with
this change, userland holding a sysfs node does not prevent the
backing module from being unloaded.
For more info regarding lifetime rule cleanup, please read the
following message.

The V4L2 API requires a unique bus_info string returned as part of the
v4l2_capability structure. These changes gather up the USB address
information, from the underlying device, into a string and report that
out through v4l2 and via sysfs (for completeness).

Use separate enum for get/store of minor number; we want pvr2_config
to go away eventually and since it really means something different,
don't use it here

This is the first patch in preparation of the V4L2/IVTV radio interface.
It does away with the assumption of only one minor per device. It also
adds a file to show the radio minor as well. This can be useful for a
program like pvr-radio.c (when it grows up), since this way it can search
for the minor of the /dev/radioX device it opened and use the video minor
of the same driver instance to get to the actual stream.
The implementation looks kinda ugly. Feel free to improve (that is the
reason behind separate patches anyway).

Take note of which sysfs files / groups that the pvrusb2 successfully
creates and only delete those specific items when tearing things
down. (Previously we just blindly tore everything down every time.)

Since kernel include autoconf.h via command line, those config.h inclusion
can be removed.

class_device_create_file is marked as __must_check, so its

If an error occurs during class_device_register, print an error message,
kfree(class_dev) and return.

Added necessary header file in order for kconfig build options to be
considered at compile time. Without this patch all options will always
be disabled, regardless of whether they are selected or not.

Rework controls internal architecture. Rework video standard
handling. This is a major change.

Arrange things in pvrusb2 so that the sysfs-using component doesn't
have to be compiled in. Control this with new
CONFIG_VIDEO_PVRUSB2_SYSFS variable. This will allow the driver to
still be used even if sysfs has not been compiled into the kernel.
Also arrange things similarly in pvrusb2 for the debug interface,
which is something that normally should not need to be built but is
valuable for bug chasing. This is controlled now with
CONFIG_VIDEO_PVRUSB2_DEBUGIFC.

This problem was introduced by the previous change. It appears that
if you try to create to sysfs entries of the same name in one
directory, then sysfs gets very angry and causes a kernel oops when
you later try to tear down those nodes. By not allocating enough
space to hold the name, we were inadvertently causing a sysfs control
file name collision...

Rework entire internal controls interface to eliminate the need for
visibly defined control IDs which must otherwise be translated by the
V4L2 public interface. As part of this work, internal structures
which mimiced various V4L2 structures (video standards, audio modes)
have been reworked to actually use the native structures. This
triggered a _significant_ rework for how video standards are dealt
with (and what is in place now should be much more flexible and
forgiving for various handling less-common video standards).

Eliminate the need to track the number pvrusb2 CIDs at compile time
from within the pvrusb2 driver. This is part of a control structure
cleanup.
