From c6330fb86fd0fed98b7e0d5792881a77b778fefc Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Sun, 19 Oct 2008 18:54:26 -0300 Subject: V4L/DVB (9327): v4l: use video_device.num instead of minor in video%d The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now independent of the minor number. So instead of using the minor field of the video_device struct one has to use the num field: this always contains the kernel number of the device node. I forgot about this when I did the v4l2 core change, so this patch converts all drivers that use it in one go. Luckily the change is trivial.
