[PATCH] device_for_each_child(): kill pointless warning noise

[Jeff Garzik]

As the last patch demonstrated, it is quite valid for a caller to ignore
the return value of device_for_each_child(), given that the return value
is wholly dependent on the actor -- which in practice often has a
hardcoded return value.

Please apply, to reduce a portion of the warning explosion seen in
current linux-2.6.git.
