cx88-dvb broken since 2.6.29-rc1

cx88-dvb broken since 2.6.29-rc1

[Jean Delvare]

Hi folks,

I have a CX88-based DVB-T adapter which worked fine up to 2.6.28 but is
broken since 2.6.29-rc1 (and not fixed as off 2.6.29-rc3). The problem
is that /dev/dvb isn't created. Presumably the root cause is the
following in the kernel logs as the driver is loaded:

I have already a pull request almost ready that will fix this issue. I'll
likely send it today or tomorrow.

Did it happen? I've just tested kernel 2.6.29-rc3-git3 and the problem
is still present.
