Another and less intrusive fix would be:

    char *name = dev->battery->desc->name;
    struct power_supply_desc *psy_desc = dev->battery->desc;
    power_supply_unregister(dev->battery);
    kfree(name);
    kfree(psy_desc);

I would much rather prefer this to the other version as it does not
leave memory hanging around, potentially indefinitely, but ultimately it
is up to Jiri. 

I must have been in some broken state of mind when applying the original 
one, thanks a lot for catching my brainfart, Dmitry!

Kryzstof, could you please send me properly formatted patch with the 
above, on top of your previous fix?

Thanks.
