Just to clarify, I think you misunderstood what I meant as you cut the 
critical line out in the reply. ...I meant heare that if 
t7xx_fsm_append_cmd returns an error, it will not make the probe to fail 
but lead to probe stalling (which propagating the error you intend to do 
will nicely address).
