If removing and reiserting the driver on some devices, tuner type will
be unset at the second time. This patch fixes this issue.

Pixelview uses a Sigmatel stac codec. It has an external line out pin,
connected to AC97_MASTER_VOL. It also provides I2S output, but using a
different volume for this (AC97_MONO_VOL).
Now that AC97 setup is finally fixed, such boards will work better.

Some boards use different AC97 setups for output. This patch adds the
capability of specifying the output to be used. Currently, only one
output is selected, but the better is to allow user to select it via a
mixer, on alsa driver.

Newer versions of hald tries to open it to call QUERYCAP.
Due to the lack of a proper locking, it is possible to open the device
before it finishes initialization.
This patch adds a lock to avoid this risk, and to protect the list of
em28xx devices.
While here, remove the uneeded BKL lock.

AC97 devices provide several input and outputs. However, before this
patch, em28xx device weren't properly allowing the usage of ac97
possible combinations. Also, several input volumes were left untouched,
instead of making sure that the volumes were set on mute state.
This patch improves support for ac97 devices by allowing to use any
inputs, and making sure that unused inputs are set on mute state.
Yet, some work is still needed to select the AC97 output.

This patch properly implements audio handling on em28xx. Before this
patch, it was assumed that every device has an Empia 202 audio chip.
However, this is not true.

Now that we have a polling task for IR, there's a race condition, since
IR can be polling while other operations are being doing. Also, we are
now sharing the same urb_buf for both read and write control urb
operations. So, we need a mutex.

Before this patch, every register setup on em28xx were dynamically
allocating a temporary buffer for control URB's to be handled.
To avoid this ping-pong, use, instead a pre-allocated buffer.
Also, be sure that read control URB's also use the buffer, instead of
relying on a stack buffer.

The first em28xx were based on i2c IR's. However, some newer designs
are coming with a polling-based IR. Those are done by reading a register
set at em28xx.
This patch adds core polling support for those devices. Later patches will
add support for some device-specific IR's.
This patch adds the same basic IR polling code used by bttv, cx88 and saa7134, and
shares the common getkey masks defined at ir-common.

Skip reading eeprom in newer Empia devices
Empia switched to a 16-bit addressable eeprom in newer devices. While we
could certainly write a routine to read the eeprom, there is nothing of use
in there that cannot be accessed through registers, and there is the risk that
we could corrupt the eeprom (since a 16-bit read call is interpreted as a
write call by 8-bit eeproms). So just be safe and bail out of the function.

From: Kay Sievers <kay.sievers@vrfy.org>
This patch is part of a larger patch series which will remove
the "char bus_id[20]" name string from struct device. The device
name is managed in the kobject anyway, and without any size
limitation, and just needlessly copied into "struct device".
To set and read the device name dev_name(dev) and dev_set_name(dev)
must be used. If your code uses static kobjects, which it shouldn't
do, "const char *init_name" can be used to statically provide the
name the registered device should have. At registration time, the
init_name field is cleared, to enforce the use of dev_name(dev) to
access the device name at a later time.
We need to get rid of all occurrences of bus_id in the entire tree
to be able to enable the new interface. Please apply this patch,
and possibly convert any remaining remaining occurrences of bus_id.
We want to submit a patch to -next, which will remove bus_id from
"struct device", to find the remaining pieces to convert, and finally
switch over to the new api, which will remove the 20 bytes array
and does no longer have a size limitation.
Thanks,
Kay

The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now
independent of the minor number. So instead of using the minor field
of the video_device struct one has to use the num field: this always
contains the kernel number of the device node.
I forgot about this when I did the v4l2 core change, so this patch
converts all drivers that use it in one go. Luckily the change is
trivial.

From: Hans Verkuil <hverkuil@xs4all.nl>
The v4l core creates four different video devices (video, vbi, radio, vtx)
and each has its own range of minor numbers. However, modern devices keep
increasing the number of devices that they need so a maximum of 64 video
devices will not be enough in the future. In addition this scheme makes
it very hard to add new device types.
This patch disconnects the kernel number allocation (e.g. video0, video1,
etc.) from the actual minor number (just pick the first free minor).
This allows for much more flexibility in the future. However, it does
require the use of udev. For those who cannot use udev a new CONFIG option
was created that changes the allocation scheme back to the old behavior.
Thanks to Greg KH for suggesting this approach during the 2008 LPC.
In addition, several bugs were fixed in the ivtv and cx18 drivers: these
drivers try to allocate specific kernel numbers but that scheme contained
a bug which caused what should have been e.g. video17 to appear as e.g.
video2.
