for patch 16/17,
Acked-by: Scott Jiang <scott.jiang.linux@...il.com>
Tested-by: Scott Jiang <scott.jiang.linux@...il.com>

Hans, I tried to use v4l2-compliance but it failed to compile. Sorry
for telling you it have passed compilation because I forgot to use
blackfin toolchain.
./configure --without-jpeg  --host=bfin-linux-uclibc --disable-libv4l

The main problem is there is no argp.h in uClibc, how to disable checking this?

checking for argp.h... no
configure: error: Cannot continue: argp.h not found
