Hi,
this is a first attempt at implementing VIDIOC_G_EXT_CTRLS and
VIDIOC_S_EXT_CTRLS, these ioclt are needed in order to make controls of
type different than V4L2_CTRL_CLASS_USER work in gspca.
An example of such a control is V4L2_CID_EXPOSURE_AUTO which a couple of gspca
subdrivers define but which can't be controlled from v4l2 userspace apps right
now.
Let me know what do you think and if you have any suggestion. If needed I will
add VIDIOC_TRY_EXT_CTRLS too.
Thanks,
Antonio
