[kernelnewbies]a question about checkpatch.pl

[Peter Senna Tschudin]

I see two problems:

1 - You are running as root. This do not cause the error message but
it is way too dangerous. Don't compile, and test as root.

2 - The correct way of invoking checkpatch.pl is from the top-level
dir. of a kernel tree. Example:
cd /path/to/linux/source
./scripts/checkpatch.pl -f /path/to/task_01.c
