From 54ad7b9d427e62f21138aacf92f8d7585344f6df Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 9 Mar 2015 13:33:58 -0300 Subject: [PATCH] [media] radio-bcm2048: embed video_device Embed the video_device struct to simplify the error handling and in order to (eventually) get rid of video_device_alloc/release.
