From 54bd5b66c87d14e250f108aad1228b905d6882f6 Mon Sep 17 00:00:00 2001 From: Kay Sievers Date: Mon, 8 Oct 2007 16:26:13 -0300 Subject: V4L/DVB (6293): V4L: convert struct class_device to struct device The currently used "struct class_device" will be removed from the kernel. Here is a patch that converts all users in drivers/media/video/ to struct device.
