V4L2_PIX_FMT_JPGL is missing a proper documentation at V4L2 API

Hi Jean-François,

I've added on our tree a DocBook patch that helps to detect the gaps between the videodev2.h header and the specs. It is complaining that a symbol is missing:

Error: no ID for constraint linkend: V4L2-PIX-FMT-JPGL.

According with videodev2, this is a "JPEG-Lite" FOURCC:

include/linux/videodev2.h:#define V4L2_PIX_FMT_JPGL v4l2_fourcc('J', 'P', 'G', 'L') /* JPEG-Lite */

This were introduced by this commit:

commit ce5b2acce60405b938d1f1f994024cde4e2cdd7e

    [media] gspca - nw80x: New subdriver for Divio based webcams

Could you please provide us the proper documentation for the new symbol?

Thanks!
Mauro.
