Hi Stefan,

I'm not entirely convinced that's necessary from a technical safety 
point of view, since I'm unaware of circumstances under which Flashrom 
will not read a chip, but will still write to it. However, I've added 
something in an attempt to exit out if the status is non-zero.

I'm unsure as to why this user is contacting you when this is my script.
