kernel-source module compiling question

["Jerry Rubinow" <jerryr@universal-imaging.com>]

I've been trying to compile the video modules in drivers/media/video, specifically videodev.c.  I'm using kernel-source-2.4.24-3.  When it tries to compile videodev.c, I get a compile error complaining the videodev.c is trying to use member "release" of video_device, which is undefined.  Looking at videodev.h, video_device indeed has no "release" member.  I don't have any other source or header trees on the machine, so I know it's not looking in the wrong place.  What am I doing wrong?
