Incorrectly detected em28xx device

Incorrectly detected em28xx device

[Matthias Bläsing]

Hello,

when I plugin my usb video grabber, it is misdetected (this email is the
reaction to the request in the module output):

It would be very nice, if this could be auto-detected. If you need more information, please CC me.

Hi Matthias,

I fixed this a couple of months ago.  Just update to the latest v4l-dvb tree.

It went into v4l-dvb on June 6th, and was submitted upstream to Linus
