[media] ivtv: Return EFAULT when copy_from_user() fails in ivtv_write_vbi_from_user()
If write() on a VBI device node fails due to a bad buffer pointer from
userspace, we should notify the application properly with EFAULT, per the
V4L2 API spec.

[media] ivtv: ivtv_write_vbi() should use copy_from_user() for user data buffers
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.

V4L/DVB (6116): ivtv: VBI cleanups and fixes
Besides some VBI cleanups this patch also fixes a subtle problem with the
VBI re-insertion stream where the PIO work handler wasn't called quickly
enough, resulting in occasional corrupt data.
Furthermore the CC output didn't disable CC correctly and at the right time,
causing duplicates to be sent.
An saa7127 fix for VPS output was also added: the wrong data was sent.

V4L/DVB (5675): Move big PIO accesses from the interrupt handler to a workhandler
Sliced VBI transfers use PIO instead of DMA. This was done inside the
interrupt handler, but since PIO accesses are very slow this meant that
a lot of time was spent inside the interrupt handler. All PIO copies are
now moved to a workqueue. This should fix various issues with missing time
ticks and remote key hits.

V4L/DVB (5345): ivtv driver for Conexant cx23416/cx23415 MPEG encoder/decoder
It took three core maintainers, over four years of work, eight new i2c
modules, eleven new V4L2 ioctls, three new DVB video ioctls, a Sliced
VBI API, a new MPEG encoder API, an enhanced DVB video MPEG decoding
API, major YUV/OSD contributions from Ian and John, web/wiki/svn/trac
support from Axel Thimm, (hardware) support from Hauppauge, support and
assistance from the v4l-dvb people and the many, many users of ivtv to
finally make it possible to merge this driver into the kernel.
Thank you all!
