[media] dvb: earth-pt1: stop polling data when no one accesses the device The driver started a kthread to poll the DMA buffers soon after probing, which relsuleted in 1000/sec sleeps and wakeups of the thread doing nothing useful until someone started feeding. This patch changes the creation and destruction of the kthread depending on the number of users.
