Please send this in a unified diff format.  The preferred method is to fetch our
development repository via mercurial:

hg clone http://linuxtv.org/hg/v4l-dvb

Then update the get_dvb_firmware script there.

Create a diff:

hg diff > andreas.patch

Send in that file, along with your description (above) and sign-off.

Thanks,

Mike
