I've applied your patches to v4l-kernel and dvb-kernel cvs, with some 
small changes (inline) :

I renamed this from enable_lnb_voltage...

You can see that i replaced (on == 1) with (on) ... If we need to change 
this back in the future, due to the chance of having possible values 
other than 0 and 1, we can change it again at that point, but I doubt it 
will be necessary right away...

I dropped this entirely -- You yourself have proven that cx24123 can be 
found at multiple i2c addresses ...

Thank you for your contributions!
