V4L/DVB (9646): em28xx: avoid allocating/dealocating memory on every control urb Before this patch, every register setup on em28xx were dynamically allocating a temporary buffer for control URB's to be handled. To avoid this ping-pong, use, instead a pre-allocated buffer. Also, be sure that read control URB's also use the buffer, instead of relying on a stack buffer.
