videodev: add support for kernels < 2.6.19
From: Hans Verkuil <hverkuil@xs4all.nl>
Add the necessary compatibility code to handle the struct device/struct class_device
differences.
It was too much work (with uncertain benefits) to convert several drivers
to handle kernels <2.6.19, so they are not built on these older kernels.
