staging: vt6656: rxtx.c [BUG] s_vGetFreeContext dead lock on null apTD. There seems to be race condition that the device is ndo_start_xmit at a point where the device is closing and apTD is NULL resulting in dead lock. Add a NULL check to apTD and return NULL to calling functions. This is more likely on 64 bit systems.
