[GIT PATCHES FOR 2.6.38] gspca core fixes

[Hans de Goede]

Hi Mauro,

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. All the gspca core patches have been reviewed
by J.F. Moine.

This pull request also includes a patch for removing all the bogus
usb-ids from the et61x251 driver as discussed.

The following changes since commit 187134a5875df20356f4dca075db29f294115a47:

   [media] DVB: IR support for TechnoTrend CT-3650 (2010-12-31 09:10:24 -0200)
