Problem with checkpatch.pl (commit f5f613259f3f ("checkpatch: allow not using -f with files that are in git"))

[Christophe Leroy]

Hi,

Runnning ./scripts/checkpatch.pl -g HEAD, I get the following error:
Global symbol "$gitroot" requires explicit package name at 
./scripts/checkpatch.pl line 980.
Execution of ./scripts/checkpatch.pl aborted due to compilation errors.

Reverting commit f5f613259f3f ("checkpatch: allow not using -f with files that are in git") clears 
the problem.
