From 50b86bac6ae6dda00faa14f7d73ae2412eacc240 Mon Sep 17 00:00:00 2001 From: Andy Walls Date: Sun, 23 Nov 2008 19:16:44 -0300 Subject: V4L/DVB (9894): cx18: Use a known open task handle when setting stream CX2341x parameters cx18: Use a known open task handle when setting stream CX2341x parameters Sometimes, we might only have VBI or YUV stream open instead of an MPEG stream. Let's make sure we use a valid task handle to perform the CX2341x control settings.
