From 467870ca26c01cb0ac84e969a78160f8164919cc Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sat, 13 Apr 2013 08:18:00 -0300 Subject: [media] cx25821: embed video_device, clean up some kernel log spam Embed the video_device struct instead of allocating it. Remove some of the annoying and ugly kernel messages shown during loading and unloading of the module.
