Good point!

Wrong, I must do that, because after that I call f71882fg_read8(data, ...)
and 71882fg_read8 needs addr to be set, notice that I'm operating on a 
temporary data struct on the stack here, which is used only to call 
f71882fg_read8, to read the config register and see if the hwmon is enabled.

I do it this way because I have an array of attributes, not an array of 
attribute addresses as the group register function expects. Walking my array 
with a loop is easier then then first creating an array of addresses (with a 
loop, or handfilling it, which is even worse) and then calling the group 
register function.

Now if there would be a group register function which I can pass the address of 
a set of attr, the offsets between all the attr (one needs to specify the 
offset ebcause we use sensor_attr not sysfs_attr which is larger) and the no of 
attr, then that would be great.
