Greg,

The patch was prepared using git format-patch. The git version I'm using:

gaston22:\-$ git --version 
git version 2.1.4

I did deleted 4 whitespaces by hand after running checkpatch.pl on the patch.
Could that drive the issue? However, I could properly apply the patch using 'git
am' from an email and get the git log right.

I'll try with a newer version of git as you suggest.
Any other check I could do before the submission? I really don't like making
noise :-(

Thanks,

Gaston
