Thanks!
Do you think it would be a problem to include the patch?

As explained the commit message, I think it's an obvious fix for the
regression introduced (with 'chomp', or similar name) for the case
when the sysfs attribute 'rev' contains only spaces -- because the
'chomp' (or similarly named) function will remove all spaces from the
string, so its size will be zero (so, the check for size greater than,
but not 'or equal to', will surely fail).

Kind regards,
Mauricio
