The w1 slave device used by this driver now has a of_node in case it

Thanks for the patch series. Having proper DT support is a nice
addition. But instead of extending the platform device hack, please
merge the w1 driver into ds2760_battery.c as it happened to the
bq27000 driver already. The intermediate platform device is completly
useless and only makes things more complicated.

Basically move all code from w1_ds2760.c into ds2760_battery.c,
drop some EXPORT_SYMBOL and make functions static instead. Then
move content from probe/remove function into add_slave/remove_slave
callbacks and drop all platform device things.

Okay, yes, that makes sense. I never understood why there are multiple drivers for this.


Thanks,
Daniel
