From 1f1988706d77083040113094a4bee2e9e1bdc34f Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 14 Apr 2013 12:07:13 -0300 Subject: [media] cx25821: setup output nodes correctly Drop the custom ioctls and enable the video output nodes again, this time using standard ioctls. The next step will be to provide a proper write() interface.
