Actually it is not removed, it is not yet added. This is a new format
for devices using the (ancient) nw80x chipset. Jean Francois Moine has
been working on adding support for those to the gspca driver. I expect
a pull request from him soon, to add this driver to 2.6.39, and thus
the define to videodev2.h . In the mean time please leave the define
in v4l-utils's videodev2.h copy (insert it manually after syncing).
