From 9d9d6baeca6f9174b8e7fd219a62a8fa09d61cc7 Mon Sep 17 00:00:00 2001 From: Andreas Oberritter Date: Mon, 13 Mar 2006 13:14:34 -0300 Subject: [PATCH] V4L/DVB (3484): Make dvb_ringbuffer compatible to dmxdev_buffer Added variable 'error' to struct dvb_ringbuffer, which is set to zero on init() and flush(). Also reset read an write pointers to zero on flush() to get less fragmented data.
