A Hauppauge HVR 4000 is used on a School On Internet Asia (SOI Asia)
project in order to carry IP traffic over ULE. However, there is an
issue with high latency jitter.
My boss, Husni, identified the problem and provided a patch for it.
The default buffer size of 32 TS frames on cx88 causes the high latency,
so our deployment changes that to 6 TS frames. This patch made the
buffer size tunable, while keeping the default buffer size of 32 TS
frames unchanged.

The original code compared "saddr_len" with zero twice in a nonsensical

check should be if "saddr_len == 1".

VIDIOC_QUERYSTD and VIDIOC_G_STD ioctls are currently not
supported in the FSL VIU driver. The decoder subdevice
driver saa7115 extended by previous patch supports QUERYSTD
for saa711x, so we add the appropriate ioctls to the VIU

Hi
This patch didn't kill Stefan's remotes and just for upload my good part of code.
1. Add some code for show IR activity
2. Add filter for IR remotes
3. Split remotes to different types.
4. Fix stop interrupt pipe when isoc pipe started.
When we decide general way of IR I'll add support our remotes.
For our customers I'll made custom temporary patch without this part.

dabusb driver were conceived as an experimental driver for a test
device. The driver never supported any shipped product, and, while
there were some updates on it in 2003, for an ancient product,
those changes were never submitted upstream.
Also, there's no DocBook for its API, nor any upstream discussion.
So, better to remove it, on .39. If later needed, we may rescue it
from git logs. For now, let's move it to staging.

ivtv_write_vbi() is used for both VBI data that came from the
driver internally and VBI data that came from the user. However,
it did not use copy_from_user() for reading the VBI data from the
user buffers.
This change adds a new version of the function,
ivtv_write_vbi_from_user(), that uses copy_from_user() to read the VBI
data provided via user buffers.
This should resolve a sparse build warning reported by Dave Gilbert.
