Hi Mauro,

And another two patches:

- v4l: use video_device.num instead of minor in video%d
- ivtvfb: FB_BLANK_POWERDOWN turns off video output

The patch 'v4l: use video_device.num instead of minor in video%d' MUST 
go to 2.6.28. When I made the minor numbers independent from the kernel 
numbering for v4l2 device nodes (i.e. videoX, radioX, etc.) I forgot to 
go through all the drivers and modify all places where 'minor' was used 
to construct a device name (sprintf("video%d", vfd->minor);) to use the 
new 'num' field instead.

Without this change you get can strange logging such as:

	vivi: V4L2 device registered as /dev/video9 

when in fact the device is /dev/video1. But the minor was indeed 9 :-)

I've CC-ed those whose drivers are affected by this change as well: it's 
important to know if you maintain an out-of-tree version of the driver 
as well. I hope I listed everyone.

Regards,

	Hans
