I have a patch pending that will actually fix the locking problem
(http://git.linuxtv.org/hverkuil/media_tree.git/commit/b7926f8ac185fe914a5a97d0206d7a3e8eb3e688)

I plan on working some more on this driver on Friday or the weekend and
post a full patch series of fixes and improvements. I recently managed to
get hold of a dt3155 card, so I can actually test the code.

Regards,

        Hans
