[CentOS] Dahdi get latest

I am trying to use dahdi complete 2.11.1 with a 4.13 kernel. - NOT working
for know reasons.
I tried applying two patches but still get compile errors. AHHH!

How do I just use git to get the latest with the fixes ????

This command did not work - I still get the errors.
git clone git://git.asterisk.org/dahdi/linux dahdi-linux

Thanks,

Jerry
