I have checked my bash history. You were right, I was using 9.2.
I have then moved to the svn folder and used ./flashrom and curiously, look at what I have got from the log file...
The file is slightly different, but it's still showing version 9.2
Launching the flashrom executable without any arguments, it tells me I'm using 9.4
I suppose there is version typo in the program itself. Otherwise, maybe the patch affect the version this way.
Anyway, It's really using 9.4 and it works very well!
