Missing sysfs cleanup.

Best regards,

Thanks for pointing this out.
To overcome this I will use sysfs_create_group after devm_power_supply_register.
Then I would not need to do this sysfs cleanup on failure of power
supply register.
I am not sure if this is good idea. This patch does not bring any
particular noticeable benefit except less lines of code. It is not worth
breaking things just for that reason...
I like less lines of code. How does the changed registration order
break anything? The changed registration order makes sense anyways,
since it then matches the (reversed) removal order.
