There are 2 main problems: [Hiremath, Vaibhav] Sergio, I do have patch fixing this issue and waiting V4L2 master to get updated first. I have attached patch here. The very first thing is this patch has been created against latest V4L2/master branch and not linux-omap branch. So there could be some gap between the merges of 2 branches. Also on regular basis (almost daily) I am making sure that all the patches which are submitted to the list are still get applied cleanly and works, obviously against their respective repositories.
