minimum commit id length when fixing a patch

[Kevin Wilson]

Thanks, Bjorn.

I added in /root/.gitconfig
...
[core]
        abbrev = 12
[pretty]
        fixes = Fixes: %h (\"%s\")
...

Still, "git log" shows more than 12 digits, like:
commit 0a528ee9a52007984fa60b0c4ef1f39fdf5edf8d
Author: Tariq Toukan <tariqt at mellanox.com>
Date:   Wed Jun 7 16:26:15 2017 +0300

    IB/mlx4: Bump driver version

Does it work for you ?

Regards,
Kevin
