Changeset 7e65d6e8f6df removed a very bad hack on mmap(). However, the fixes
weren't considering usermap and overlay memory models. This were breaking
direct reading from /dev/video?, used mostly by mpeg aware drivers.
Thanks to Steven Toth <stoth@linuxtv.org> for reporting the issue and
bissecting it.

This driver supports cameras with USB ID 174f:a311 or 05e1:0501,
and the ov965x sensors. These devices are found in some Asus laptops
and probably somewhere else.
It is based on the stk11xx driver written by Nicolas Vivien

saa7134: remove the Avermedia Super 007 from eeprom detection
The card made it into the Philips' Tigers eeprom detection and falls through.
Since it has attracted already others to follow, which are wrongly identified
as TIGER_S then, move it to the usual analog initialization.

Setting force_init=1 bypasses the friendly auto-detection by polling the
status register, and instead attempts to initialize the qcam directly. Not
friendly to other parallel devices, but much more reliable than the
auto-detection.

The cx23885/7/8 PCIe bridge has an internal AVCore modelled on
the cx2584x family. Many of the registers positions are identical
but some moved. The register values are also different because
the different bridges run at different clock rates.

In order to videobuf_iolock to work, mmap_mapper should be called first.
Otherwise, an OOPS is generated.
On some cases, .mmap file handler used to took some time to be called. On those
situations, mmap_mmapper() were called after iolock.
This patch properly waits for mmap_mapper to be called, otherwise generating an
error.

IR were not working for Winfast XP 2000 TV.
Gabor Nyekhelyi <n0gabor@vipmail.hu> wrote a hack some time ago:
http://marc.info/?l=linux-video&m=116362609323281&w=2
This patch fixes CodingStyle and commits the hack. I suspect that the proper
solution would be to find the proper mask_keydown for this IR. Anyway, better
to have this patch as a workaround.
Thanks to Stafan Talpalaru <stefantalpalaru@yahoo.com> for pointing the issue.

Before this patch, only Vendor Class audio support were loaded. This means that
