From 6da6bf5e43f409672f5525657ff59282e160c59f Mon Sep 17 00:00:00 2001 From: Andy Walls Date: Sat, 21 Feb 2009 19:53:54 -0300 Subject: [PATCH] V4L/DVB (10760): cx18: Fix a memory leak of buffers used for sliced VBI insertion We leaked buffers every time a device was removed, if the user had enabled sliced VBI insertion into the MPEG stream. MythTV uses that.
