Hi Florian,

I'm using OpenSuse 11.4 with the tumbleweed kernel 3.0, unfortunately my
DVB-USB Box stopped working with this kernel.

I goggled and found your patch at:
https://patchwork.kernel.org/patch/1029612/

Jiri Slaby from OpenSuse build a testing kernel for me with your patch
applied, but the patch did not
fix the problem,
please have a look at:

Thank you,
Markus Stephan


Hi Markus!

Thanks for testing that patch. Here is a fixup to it. Can you give that
a try? It's not the final answer (the naming of the functions sucks) but
should work (tm).

(I forgot to fix up the usb_inout_op call sites in the vp702x-fe.c file and
thus the
buf_mutex was not initialized. With the attached patch applied,
everything should work.)

Maybe Jiri can whip another kernel up for you to test?

Regards,
Flo
