staging: vt6656: covert BSSvSecondCallBack to delayed_work.
timer to delay workqueue. sTimerSecondCallback -> second_callback_work The delayed work queue is declared in device.h This timer is very heavy on the system. Improves over performance of driver and reduce the atomic area of driver. Signed-off-by: Malcolm Priestley <tvboxspy@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
