[PATCH 4/5] kobject: kset_uevent_ops: make name() callback take a const *

[Greg Kroah-Hartman <gregkh@linuxfoundation.org>]

The name() callback in struct kset_uevent_ops does not modify the
kobject passed into it, so make the pointer const to enforce this
restriction.  When doing so, fix up the single existing name() callback
to have the correct signature to preserve the build.
