From 79721c4957171ea0fdaf1fa6565e7699dad1b76e Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sat, 23 Aug 2008 10:47:41 +0200 Subject: v4l2-dev: add video_device_release_empty From: Hans Verkuil Add a second release function: video_device_release_empty It can be used by drivers that have statically allocated video_device structs. Its use usually, but not always, indicates laziness on the part of the driver programmer.
