It looks like the tda9887 device is erroneously clamining the same i2c device 
as the ALPS TDMB7 device. I've seen this as well with the cx88 DVB-T cards. 
If you can avoid loading one of those modules, that would be the easiest way 
to fix it.

Otherwise.. umm, you'll either have to hack something in yourself to stop the 
tda9887 from jumping on the bus, or wait for the new code refactoring + 
kernel i2c fixes.
