We need to import the 'sys' package since the script has called
sys.exit() method.

Thank you for making those changes!

I should have mentioned that this probably warrants a Fixes: tag, which
can be generated by running:

$ git show -s --format='Fixes: %h ("%s")' 6ad7cbc01527223f3f92baac9b122f15651cf76b
Fixes: 6ad7cbc01527 ("Makefile: Add clang-tidy and static analyzer support to makefile")

as that was the patch that introduced this issue. I personally have a
git alias for this as it comes up enough.

$ git config --get alias.fixes
show -s --format="Fixes: %h (\"%s\")"

I do not think this warrants a v3, just something to keep in mind for
the future.

Fixes: 6ad7cbc01527 ("Makefile: Add clang-tidy and static analyzer support to makefile")

Applied to linux-kbuild

I'm quite sure I've run this script before; how have we not noticed
such an issue before?

Nobody hitting the error paths in this script?

$ cat test.py
import sys

if __name__ == '__main__':
a = int(sys.argv[1])
print("a = %d" % a)
if a == 2:
printf(os.uname())

$ python3 test.py 1

$ python3 test.py 2
a = 2
Traceback (most recent call last):
File "/home/nathan/test.py", line 7, in <module>
print(os.uname())
NameError: name 'os' is not defined
