Subject: greybus: get rid of a compile warning

greybus: get rid of a compile warning

The compiler has no way of knowing whether a called function will
actually assign something to the object whose address is passed as
an argument.  So it must assume it won't happen, and this leads to a
compile warning.  Fix this.
