[PATCH 2.4.23-pre8] meye driver update

[Stelian Pop]

Hi,

This patch updates the meye driver with:
	* some documentation on a forth camera model (unsupported)
	* headers cleanup backported from 2.6
	* irqreturn_t constructs backported from 2.6
	* use the new videodev video_device_alloc/video_device_release

Marcelo, please apply.

Thanks,

Stelian.
