Just a little doubt. caller means the function which is calling this
dgap_parsefile() or you meant the user?
The function which is calling this dgap_parsefile() is just checking if
it has received 0 or something else. Something else is error and it
rerturns -EINVAL for all types of error (ofcourse that is also wrong).
So the user will see -EINVAL for all types of error in dgap_parsefile().
