Hi,

When there is no memory left for creating all IFB devices (requesting
by user), a oops happens on the system.
Please find enclosed a patch to solve this.


Regards,
Nicolas


[IFB] After ifb_init_one() failed, i is increased. Decrease
it before entering in the loop for freeing the other ifb devices.
