Hi Mauro,
While working on something else I suddenly saw that the VIDIOC_OVERLAY support
was broken in 3.6. The vidioc_overlay op in v4l2-ioctls.h receives an unsigned
int,
whereas the ioctl table in v4l2-ioctls.c assumed that it would be an unsigned
int
pointer.
To fix this a small conversion function was made.
This patch applies to 3.7. By checking 'v4l2-core' to 'video' in the path of
the file this patch will also apply to 3.6.
All other ioctls that do this dereferencing are fine, it's just this one that's
failing.
Regards,
Hans
