[GIT PATCHES FOR 2.6.38-rc1] gspca locking fixes and moving over usb-ids to sonix? drivers

[Hans de Goede]

Hi Mauro,

Here is a new pull request including all the patches from my previous request:

"Please pull from my tree for a number of gspca core fixes. While looking
into the issue you were seeing with qv4l2 I also found a bug in the
gspca core which made it impossible to switch from userptr to mmap
mode with qv4l2 and gspca. While fixing that I also ended up fixing
some locking issues."

On top of that there are patches removing non supported bogus /
non supported usb-ids from Luca's et61x251 and sn9xc102 drivers.
Combined with some fixes / bridge variant unification patches
to the gspca sonixb and sonixj drivers allowing moving most
usb-ids to use gspca sonix? by default.

I've asked J.F. Moine to review all these patches and he has
and responded to me with an Acked-By email hence the Acked-By
tag on all of them. Except for the last one which I did after
he reviewed the 2 patch sets.

The following changes since commit 0a97a683049d83deaf636d18316358065417d87b:

   [media] cpia2: convert .ioctl to .unlocked_ioctl (2011-01-06 11:34:41 -0200)
