Subject: [PATCH 2/2] power: fix incorrect unregistration in
 power_supply_create_attrs error path


In power_supply_create_attrs(), we create static attributes as referenced
by power_supply_static_attrs[i].  After that, if we fail, we unregister
via power_supply_static_attrs[psy->properties[i]].  This is incorrect, as
psy->properties has absolutely no bearing on static attribs.  This patch
fixes it to unregister the correct attrib.

Another line which was unnecessarily line wrapped is also unwrapped.
