The rc variable is initially used to store the return code from the
ibm,update-properties rtas call which returns 0 or 1 on success. A return
code of 1 indicates that ibm,update-properties must be called again for the
node. However, the rc variable is overwritten by a call to update_dt_prop
which returns 0 on success. This results in ibm,update-properties not being
called again for the given node when the rtas call rc was previously 1.
